PS5 controller not working on S21 Ultra?

[BigMosley]

Hey figured I'd grab a PS5 controller before I get the system since I'll end up buying another single controller anyway to play some COD Mobile with it on this S21 Ultra beast. It connects just fine to the controller but then when you play the game it constantly pans around and it's unplayable. Can anyone else with a PS5 controller and the Ultra test this out?
