The other night mystadia controller randomly started vibrating non-stop, and the stadia home button was flashing red. Now my controller won't charge, won't turn on, and won't function at all. Anyone know what I should do?
@ElectricZap Are you sure it was flashing red and not orange? Could possibly have been bricked during the firmware update.
