Are you using https? On mine the app doesn’t allow just http.

Came here to say this too

Keep notes on what you do including outcomes. You can always reinstall, skip all of the extra crap you didn’t need to mess around with and have a good clean system without having to back track.

Maybe a dumb suggestion, but shouldn’t spotify + ublock still work on firefox for android?

This is actually the strength of federation and open source. There is no central authority to stop any use. We individually have control over what we interact with in the usual way and we (collectively as an instance) have the same control. If you don’t want to belong to an instance that blocks anyone, join a different instance or even start your own. This is just one place of many. Each of us can find or create the one that is right for us.
