Is this just me? Everything works perfectly, but if the controller turns off and on again while a game is running, it’s no longer recognized, and this forces me to restart the game.
I don’t know how useful it is but I tried to join the input group, nothing changed.
I think the issue is how the games are programmed. Some games check which controllers are plugged in only at start and some do regular checks during runtime.
