update: with help from my distributor (Cloud Break Optics, Seattle) I was able to this fixed, at least temporarily. They suggested I download the SkyAtlas app (called ASI Mount app in your documentation - please update that - I would never have known the name had changed) to my Android phone, enter the location coordinates, and somehow synch them to the mount. Then the red/green alternating would settle down to red or green. Bluetooth would not work, but Wi-fi did, so I was able to do that and the light stayed red. Then I was able to launch NINA and sync the mount to NINA.
When the ASCOM driver came up, we found another problem. 3 days ago I had picked COM4. I was not seeing the correct info on the ACSOM window (AM5, not AM3, other wrong info, no serial number). We checked device manager and saw COM4, 6, and 9. The first two were USB Serial Port, but COM9 was USB Serial Device. We picked COM9 and then got the right info - AM3, serial number, etc. In the advanced section we saw the location info and all the other data was correct.
I did all this in my garage. Now I have moved it outside and powered the mount and everything else up. But the red/green flashing is happening again. I tried Wi-fi, but my phone now cannot see the mount. I tried Bluetooth, and it did find the mount (AM3_e1ba01). When I tap it, I get message that an app is needed. It tries to pair, but then says it could not pair, make sure the device is ready to pair. I also note that in the SkyAtlas app it says to confirm pairing on the mount by pushing the BT button. That is on the AM5 - there is not BT button on the AM3, just the blue light.
So I still have several problems and once again cannot use the mount tonight.
