This might just be a bug with the 360 degree wrap around. Notice that 266 degrees east of north on the compass is the same as 94 degrees west of north. So, both of them point to the same direction.
There was another bug (has to do with reporting wrong E vs W flag) with my mount, but that was fixed in the current v1.3 release. A remaining bug has to do with reporting my UTC offset as zero. (The ASIAIR has a knack of reporting values it cannot display as zero, instead of as "not available.")
While the above may not cause any problem (ZWO needs to fix the bug, nevertheless), your other problem (not being able to sync phone location to mount) is worse.
The first sanity check is to see if Location Services in your iPad gives location permission to the ASIAIR app. OS Settings > Privacy > Location Services should be turned on, and the permission for the ASIAIR app should be either "While Using the App" or "Always."
My three mounts are different from yours, so I wouldn't be able to help with AVX specific stuff. If you can slew the mount from ASIAIR and not have any meridian flip problem, I would just not touch the "sync to mount" button.
BTW, once you start plate solving, you might find that SkySafari becomes superfluous, as long as the objects you need to find are in the ASIAIR database. You can manually enter coordinates, if they are not in the database.
With the ASIAIR, SkySafari becomes pretty much just eye candy, or used as a planetarium when planning the night's schedule. Speaking of which, if you like eye candy and have two iPads, you can connect one to ASIAIR and the other to SkySafari (using the ASIAIR's network) and watch both at the same time. SkySafari will track ASIAIR when you perform a goto after plate solving.
Moreover, star alignment is only needed if your mount needs it to open up its data port. With two of my mounts (a Takahashi and a RainbowAstro), I do not need to do any star alignment -- a simple plate solve and goto gets me to the target object. If your mount needs to be star aligned prior to connecting to a computer, just lie to your mount that it is star aligned, connect to ASIAIR, and just use plate solve to locate the telescope's pointing.
