Free, Russia, Xiaomi Mi A3, Android 10
Issue started off with "no internet connection available" when I was on either wifi (tried multiple networks) or mobile data. Tried toggling offline mode on/off, as well as airplane mode. No luck. Restarted phone. No luck. Tried multiple more times, still "no internet connection available". Double checked my battery optimization and a data settings to make sure Spotify had all necessary permissions.
I tried reinstalling the app (twice). And now I can't even login because it says I'm offline
"You're offline. Check your connection and try again." Only option is --> OK
I have 2 accounts and I can log in second account. Finally I can log in main account from mobile browser and desktop.
