So, I used to be simply taking part in Overwatch utterly positive and mid-match my A, B, X, and Y buttons in addition to each left and proper bumpers stopped working utterly. The left and proper triggers work in addition to the joysticks and the X, however nothing else. I attempted taking the batteries out and plugging in so I can attempt to replace however now can not register to the Xbox as a result of the buttons aren’t working. Any ideas?
