I don't know for sure if it's thia is the app problem, or the issue is with Spotify itself that maybe restricted login from unofficial apps after yesterday being down, but I can't login to my account with JetiSpot. It keeps saying "Incorrect username or password", even though it's working without problem on official app or site.

I'm on Android 12.1 (L), rooted and using VPN, if any of this information can help.
