Downloaded the current version of MCPE to my Google Pixel XL, and I am unable to use the Xbox One S controller connected via Bluetooth to properly control the game. Once in a game, the left stick will control movement, but nothing else works. None of the buttons or triggers are recognized, nor is the right stick. The phone recognizes the controller as an input device, and I can use the buttons to control things within the OS (menu navigation and such), so the problem appears to be isolated to just Minecraft.
