On my lock screen, the Spotify controls no longer appear as a permanent notification while music is playing. They are still present when I expand the notification bar on an unlocked phone, however.

I have tried closing and reopening the app, logging out and in, and also uninstall/reinstall.

All Spotify notifications are enabled in-app and in Android settings both (Settings > Lock Screen > Notifications) and  (Settings > Apps > Spotify > Notifications).

Attached image is what I see when I expand the notification bar while music is paused, and what I would expect to see on the lock screen.

I suspect this has something to do with a recent Android update which changed Samsung's "OneUI."

Info:

Samsung Galaxy S20FE 5G

OneUI version 4

Android version 12

Spotify app version 8.7.4.1056
