Luxo Looks like ASIAir is only suitable for the toy refractors on AM3/AM5.
Sorry that it hasn't worked for you and those in your club. Glad you can get going - even if it's not ideal - with other methods.
Something to try is re-doing focal length. This would involve setting the Main Camera focal length to 0, slewing to area past 5° of the SCP/NCP, taking a single exposure (2 seconds I think but it may be more/less depending on your setup and use of filters) in Preview Mode, then tapping on Plate Solve. If it succeeds, it should calculate the focal length. Then you tap Sync.
Thing to remember with plate solving - for it to work you need to have the focus to be good (not refined, but good), Gain set correctly (Main Camera Settings), and Center EXP time set correctly (Telescope/Mount Settings - filters can effect this as well so the time needs to be set accordingly which may require some experimentation), and the FOV between 2 and 33 degrees (determined by your scope, camera, and use of reducer/barlow - use this website
https://astronomy.tools/calculators/field_of_view/ and set to Imaging Mode).
There are plenty that it works for. They've said so on here, in the Facebook groups, and on Cloudy Nights.
I'm doing unguided EAA with a C8 SCT with f/6.3 focal reducer, ASI294MC Pro camera, on a HEQ5 Pro mount. It works for me.
Obviously you'll hear more from those who it doesn't work for than those who it does.
Anyway - I created a thread about the 2.4.4 App/Firmware release (since ZWO didn't for some odd reason) here: https://bbs.zwoastro.com/d/25293-unannounced-asiair-v244/
I, myself, haven't upgraded yet so am still on App version 2.4.3 for Android.
