Since the latest update for Rocket League, my controller does not work in the game, but the controller does not work in the menu in the game.
Are you still doing?
I tried with Switch and a pc controller with Xbox layout did not work, everything is set correctly in the stream.
Only keyboard works and controllers only work in the menu.
I have an Xbox One controller and I always have it connected with the cable and it works with me. That's the only thing I can think of that could help.
