Hello,
When i try to play on my CCU it just freezes when I am in the game, and also sometimes when I try to launch a game it just loads trying to find connection. Casting YouTube videos works. When I click the Stadia button it says that I am not playing a games and that I am offline. But when i play on the chrome browser everything works. My CCU is connected via Ethernet with 100 Mbps download and upload. I also tried connecting the chromecast to WiFi but the problem is still there.
Does yours work yet. So far the response to this issue, and my ticket has been mostly ignored...
