What mount are you using? I have been using an Alt-Az mount (RST-135 in Alt-AZ mode) with the ASIAIR Pro for about a year. I have no problem. I first {Home} the mount, select an object in Preview mode, it slews to the area of the object, plate solves, and eventually centers it. No star alignment is necessary which is why I love this combination. Otherwise I would have to do a 5-star alignment with this mount to get good accuracy.

Sky Watcher Virtuoso GTi . Thanks, I will try what you suggest.
I have yet to be able to activate the "Tracking" button on the ASIAIR. I have to begin tracking with the APP, but then slewing with the ASIAIR controls deactivates the tracking and I have to go back to the app and toggle it off/on to begin the tracking.
John D,
I tried you suggestion, and the alignment seemed to just about work. There are still problems.
1) It took 10-15 minutes to GoTo to my target object, kinda. There were tons of plate solving issues. It world fail plate solving many times before there was a success. It finally did move near the target, but it failed the plate solve several times until it gave me an option to "retry" or "stop". I stopped at that point. Plate solving while in the preview mode work just about everytime. So I don't know what the difference between the Goto plate solve failing, and the preview plate solve working fine.
2) The star field slowly moved out of view. It seems that tracking is not turned on by ASIAIR, and if I turn it on with the synscan app it will stop tracking as soon as I move to another goto object with ASIAIR or sometimes the tracking just turns off. Would be nice to turn on the sidereal/lunar tracking @ 1x,0,75x,0,5x on the ASIAIR.
This is a 6" dob on a "table top" mount. Are you putting the scope and mount on a table or do you have some sort of tripod upon which you place it? I don't understand the multi-minute plate solving issues you are having. I am suspicious of the stability of the table top setup. Maybe someone else will pipe in and comment on this.

The-Vman Plate solving while in the preview mode work just about everytime. So I don't know what the difference between the Goto plate solve failing, and the preview plate solve working fine.
I quite often have the plate solve work from a preview but fail in PA without moving the telescope. I believe this is because of the low res image the ASIAir uses when doing a PA plate solve, which I think is to speed things up. I wouldn't be surprised if this is what happens when centring a target.
I assume if you disable centring and just goto and then plate solve, align and goto, it works first time?
Its on level table. I was able to slew to M31. Here are the steps
1) Face the telecscope "north" and roughly point at polaris.
2) In Preview mode, set exposure to 1 second and capture an image.
3) Tap on plate solve. It solves in seconds and give me an option to "sync mount". I sync.
4) GOTO m31. It can take several minutes to go there, most of the time the values are very slowly moving, so I just tap "stop"
5) I grab another image in preview, tap on plate solve and then "sync and goto m31".
6) I do this several times until the target appears.
7) on my phone, (ASIAIR App is on a tablet) select "sidereal" tracking.
8) Back on the Tablet, tap live stack and proceed to grab an image.
I think there is an issue with the goto slew, as it seems to take way too long. And also there seems to be an issue with the plate solve within the goto slew. As it works just fine when I do it manually like I described above.
The-Vman Please upload the runtime log, so we can find out what happened while doing GoTo, then try to optimize it.
A few points:

Thanks to everyone who has helped so far.,
Yes the scope is balanced. The Pro camera does have some weight, and the ASIAIR is on the opposite side along with a small counter weight, that allows me to balance the tube. The focal length shows 749 on ASIAIR. I do not get an option for alt-az or equatorial in synScan, it shows up as alt-az. I first tried the north with the tube parallel to the ground. So I was trying other positions just in case.
If I use the SynScan app alone its works perfectly. Granted, this app is for "Visual" astronomy. From home position it moves the telescope close to the target, then I manually center, then press the "its centered" button on the SynScan app, it begins to track the sky and all is well. Each additional GoTo becomes more accurate in getting the telescope to center the object. I was gifted a huge 1kwh portable power station. I can use this for weeks with the Telescope.

I was unable to find any logs. I have an SD card, and there are no log folders or files there. I have also connected the ASIAIR to the ethernet (wired) and was able to Samba into the device and look at the drive there. Also no logs. I noted in the ASIAIR manual that logs only appear after a completed "autorun" which I have not initiated any. I have not been able to SSH into the system, as the default port is closed or SSH is closed.

I disabled centering, started at home position and ran a GOTO. It came close, so I plate solved and had it "sync then GOTO". Repeated a couple of times till everything was centered. I did notice that as I continued to GOTO to different objects in the sky, the position seemed to alter, cant pinpoint when it happened. Like GoTO M31 00h 44m 00s / +41 23' 36" Current RA/.DEC 04h 29m 42s / +80 42' 05". I mean way off and it was pointing to the wrong point in the sky and the telescope was not slewing, if I then used the SynScan app and had it GOTO m31, it was able to track to the correct position. So after that I just turned of the mount, started over and the ASIAIR worked fine again.
One interesting comment is that if in preview mode I attempted to capture with an exposure time of 2+ seconds, it would not plate solve correctly. Most of the stars appeared as streaks. So 0.5 to 1 second kept the stars from appearing as streaks, since the mount's tracking was off at this point. Maybe in the "Auto Center" option, allowing us to select an exposure of less than 2 seconds might help. Change the buttons to a slider there.
So one thing I noticed is I need to still use the SynScan app to at least align the first star or its Tracking algorithm wont work right. I was able to view and live stack the Pleiades last night using the following steps.
1) Set telescope to home. North and tube parallel with the ground.
2) use SynScan app to Goto first object. When it told me to manually center ...
3) I used the ASIAIR app and captured an image in preview with 0.5 exp. Made sure the correct target was in goto. Plate solved and it asked if I wanted to align then goto target. I tapped that. After a couple of iterations, my target was visible.
4) Back on SynScan app I pressed "object centered" and made sure object was tracking. I have to keep this app on as tracking is described by the SynScan manual as a "long event" and requires the app to be active or run in background mode or the tracking will stop.
5) Now on the ASIAIR app I switched to LIVE and with the object now tracking I started Live Stacking 2-5 second exposures. After several minutes I got a nice sharp image and saved the live stack.
It would be nice if ASIAIR would alt-az align then begin tracking from within ASIAIR. And allowing faster exposure times in the auto center option might solve the constant plate solve fail issue.
OK so it does work with the combination of the SynScan Pro app and the ASIAIR. That looks like what you have to do. I can find no tutorials on running the Virtuoso AZ-GTI with the ASIAIR, so you are kind of flying blind. I don't know why there is a problem with 2s plus Preview mode unless tracking is off at that point.
It has been a while since I have used the SynScan app with an older Skywatcher mount I have. The mount had both EQU and AZ capability so in the app I was presented with the option to chose which one I was using. Apparently the app recognized that you were AZ only.
I thought there was an option in the app to disable screen shutdown, but I also did it through the main tablet settings (I was using an iPad). I did not have an ASIAIR then and only needed one device to run things, although at one point if you wanted to use SkySafari as well as SynScan Pro, it required two devices.
The only other thing I can think of is that your mount is trying to communicate simultaneously with two separate devices which also might confuse things. There is an option in the SynScan app called "Pointing Model Sharing" or "PM Sharing". This can come into play when more than one app is trying to control the mount. You might want to have a look at that and possibly turn it on and see if that helps.
Keep giving it a go and let us know how things come out.

The-Vman im having the same issues. What driver are you using? So to confirm the only way you are getting it to work is with the Synscan app? I will try that tonight.
I was able to at least get it to "sound" like it was trying to track with the Skywatcher Az-Gti/Synscan Wifi driver and it could get close to the target without going in crazy directions. But it would fail trying to auto-center and wasnt tracking, even though it sounded like it was trying.
thebruce The best success I had without the Hand Controller was to use the "SkyWatcher Virtuoso Alt-Az" mount or the "SkyWatcher Alt-Az Wedge" mount along with a tablet running ASIAIR and my phone running SynScan App. I used the phone to turn on the tracking after each GoTo. I turned off the "Center GoTo" and just manually plate solved after I "Previewed" for 0.5 to 1 second exposure. Since tracking is off at that moment any longer of an exposure and you start to see streaks.
Once my object is pretty much centered, I used my SynScan app and toggled the tracking off/on to engage the tracking properly. Sometimes more than once. It was then tracking. Making the mount move from the ASIAIR app can cause the tracking to stop and you have to re toggle the tracking on the SynScan App.
Below is a link to what I was able to accomplish with Hand Controller. I hope that ZWO will fix the SkyWatcher Virtuoso Alt-Az in the near future.

On the SkyWatcher AZ-GTI/SynScan Wifi mount is your Azimuth flipped? Does pressing left turn the mount right and visa-versa for you as well?
The-Vman thanks for the note. I converted to EQ mode with a wedge and the EQMod driver and appears to be working. I had cloud lasts night so wasnt able to plate solve to confirm, but looks like progress.
However I would still like to use it in Alt/Az mode and ZWO needs to prioritize this - and clarify its AZ-GTi instructions to state it will only work in EQ mode. It appears there is a working INDI driver thats working with Stellermate.
@ASIAIR@ZWO can you let us know timing? Happy to help test.
The-Vman re your question, here are the results I had testing the other drivers:
