This happened to me in a couple of games (Nioh being the latest): after playing the game with the deck docked (using an external monitor and controller), I can no longer play it on the deck itself because it seems the game no longer registers the deck’s buttons. Has anyone else experienced this?
If a controller is still connected (Bluetooth?) it may be a controller order issue, you can try reordering them.
the controller was not connect, but controller order did fix it
