First I tried using an Xbox one controller. it works fine on my chromebook, but with my pixel, it works throughout the menu fine but when I get to the screen saying press a to play, the a button doesn't do anything. I can press b to go back press start everything except the a button. so I decided to buy the razer controller for my phone and I'm having the same issue. can anyone tell me what the problem is and/or how to fix it?
Are you using the Xbox Series X controller with the share button or the Xbox One X controller?
it was the Xbox one controller. I don't understand why I would be having the same issue with the razer controller tho
Good point, it shouldn't be happening on either of the those devices. I highly suggest going to the help page located right in the Stadia app.
