I am using the moonlight/sunshine method to open Big Box on my ATV 4K as well. However, my xbox controller which is paired directly to my ATV doesn't seem to work when playing games in Big Box. For example, I have tried launching a game using ryujinx emulator that I have configured in Big Box, but after the game is loaded, none of the controls on my xbox controller seem to work. They do work fine for navigating the menus in Big Box though. Can someone please help me fix this.
