I connect Stadia controller to my phone (Pixel 3) with USB-C. In the controller screen it says the controller is linked. I can move in the menu screen with the controller, choosing games to start.
However, when game start and it requires "Push Any Button" or "Press A to start", it doesn't respond at all when I press buttons.
I had no problem connecting Stadia Controller and my phone before. I did it and played the game with the same USB-C cord and controller to my same phone.
I tried to factory reset the controller but still same.
I appreciate any help. I want to play Stadia outside of my home, but I cannot do it because I cannot connect my controller wired.
