I bought Stellarmate OS 3 days ago as it has a mobile app that I wanted to use. Coming from Astroberry I thought that all that posts that it is unusable are fakes (you just need to setup everything correctly as in Astroberry I thought). However, now I understand why there is many negative posts. My experience went from good to bad, I managed to run everything on the first one or two boots, and then features just deasppeared.

1. When I loaded first time I got a crash with toupcam driver [Warning: Spoiler!]
2. Next I pressed update through the VNC (it was the latest version already but some update was pending) and after update kstars shortcut disappeared from the descctop as well as 2 other shortcuts. (fixed)
3. So I had to reinstall stellarmate and here comes "no hotspot" issue. I tried 3 different sdcards (usual, A1 , V30) and both 32 and 64bit versions. Finally I have some sdcard that works. Thats fixed.
4. Then I could see device and connect it to home wifi but got a message "EkosLive is down", tried all steps in faq - no luck. Tried to start ekos manually through VNC - no help. Reinstall app - no luck. Decided to reinstall os again (not fixed)
5. After 3 other fresh installs app deceted device only once(!) . No I can't connect though the app at all in different os versions(32/64 bit, different sd cards), I can't even access the step "EkosLive is down", I tried to enter IP manually but the app doesn't see it(!), BUT I can access through МТС from the same smartphone(!) and through bonjour discovery name(!!) in the browser! So the issue is ddifenetly in the app. Not even a reinstall helps. (not fixed)

So I have to use Stellarmate OS same as Astroberry through VNC, the only benefit (the app) simply doesn't work for me.

PS As a mobile developer I've seen lots of apps, lots fo legacy code, but I have never had such bad experience as a user. Probably that's React Native issue, probably some internal logic. More effort should be put into mobile, it's such a waste of opportunity
