I'm not sure what happened but during a game I switched the environment. Now, I cannot figure out how to get the Xbox's Xbox Button, Environment Selector, or Settings cog to show up. I can't adjust the screen, anything, I am just locked into the xbox's game and I can't get back to the main menu of the xbox (the game itself offers no quit option in the menu). When I re-launch the app it goes right back to the point where I'm stuck, is there a keypad combination on the controller to bring-up the environment/settings/xbox button?
