Phone just stopped doing sounds from notifications on cover screen (FLIP 4)

[Phalanx]

My flip 4 just stopped making sounds when closed. I get the notifications just fine on the cover screen but they just vibrate and produce no sounds.

I'm tried to thinker with every notification configuration on the phone and it just won't work. Any help is appreciated as this is driving me crazy.

Info:

I use Cover Screen OS and already tried uninstalling it. No change
Not Disturb is offf
Battery Saving is off
