Well, I don't see any issues with Stadia Controller working with my
Macbook for instance.The problem looks like to be with Chromecast with
Google tv 4k and BLE devices (stadia controller in this case).
Yeah, I did reset as well and still the same problem. Controller pairs
and works fine on the first pair. After turning it off and then back on
it connects but doesn't react on any button. I need to reset it and pair
again to make it work. Unfortunate...
