Bluetooth audio not connecting?

Not sure if this is a phone issue or a car issue. I have a 2020 elantra. Bluetooth connects for calls only (I have a S22 ultra) and the Bluetooth audio button on the main infotainment page is grayed out. I have unpaired, repaired it and I'm still having the problem. It was working fine this morning. The phone connects just fine to other BT devices. Any help would be appreciated.

UPDATE: Oddly enough it fixed itself and started working again. Weird. Thanks for the suggestions.
