Is there a way to edit a post? My previous post said "I passed Project Streaming with an Excellent", it actually says "Great". I think in Stadia the best connection is "Excellent" which I wished (and should be getting) I had.
I'm happy to report a solution to the controller unlinking problem if you are using Google Wifi. Using the Google Wifi app, reset the network. This should stop the controller from loosing it's link during gameplay.
