My Left controller stopped working all of the sudden while I was playing after I came back from the bathroom: I cant pair it, It does not track, the light does not turn on while trying to pair, I cleaned it out a bit not with water or any damaging items, but did not help, I checked batteries, swapped batteries from each controller one is at 80% one is at 100% so it should work with those my right controller does and I have no idea what to do other than take it in to get replaced.
