Every time i go to play any game from Stadia it tells me to update my chromeos so i got to do that, my chromebooke tells me that its already up to date so i just restart the chromebook and go back into stadia and it still tells me the same thing. Please help me fix this issue all I want is to some games
What model is your Chromebook? If it's very old, it could be that it has already reached end of life on Chrome OS updates.
