PC, and I used a King Kong 2 on my Switch when I owned one. I no longer do. I also texted it on a Deck(same same), and an Android phone for the hell of it.
I’m not sure about the PS5 controller situation, but I do know they work universally across all of the 7th gen devices.
Sorry, sometimes I forget the current Gen is even a thing considering there aren’t really any memorable games or happenings going on beyond overpriced hardware and live service games.
