I noticed a few days ago my right controller LED light remains lit. The controller worked so I didn't think it was an issue. However, today I notice that it is on 24/7 and has drained the battery. Anyone know how I can fix this issue? I unpaired and removed the battery for 15 minutes. As soon as I reinstall the battery the light goes on and remains on. I can pair the controller and it does blink during the pairing, but remains on.
