Apple TV 4k can't play videos on youtube

• Try if it makes a difference for being signed in, or not.

Try this for any misbehaving app:

• Force-quit the app, then relaunch and try again.
• If the issue persists, restart the device, then relaunch and try again.
• If the issue still persists, delete the app, re-download and try again.
• If the issue still persists after that, then contact the app developer for further assistance.

(The YouTube app on my Apple TV 4K doesn’t seem affected by the same issue, although I wouldn’t know what videos you tried.)

I WAS able to play videos when I don't sign in, but once I do it fails and continues to do so even if I log out again. I've rebooted Apple TV and deleted and re-installed YouTube app. This just start a couple days ago.
