I can see the hud I see what song is playing and I logged in but I can't control it at all not even the volume. Am I doing something wrong? This is my first time using this mod so idk. Please help!

Also, I use fabric 1.20.1 if that helps.

Try restarting, if you are using Spotify then controls on non premium accounts cant be used as Spotify locks that API behind premium accounts

Okay, so I just now realized it said it requires Spotify premium... Sorry!
