Mine also stops working but it’s a firmware issue. Recently I found out, when I cut out the power by disconnecting the battery from a 2015 controller and plugged back in everything works like a charm until I reboot or shut down the console. So I made a workaround. I drill a hole on a controller and connect a switch to the battery. It was annoying the old way now I just hit the diy switch off and on and everything works fine [br]
