Mine works on my computer but my Roku tv refuses to connect to my account
Yeah, I was unable to log in to use the YouTube app on my AppleTV 4K set top box.

I had the same thing.
It kept prompting me to sign in with Google.
When I turned off my cell phone, for some reason it let my Roku back in,,,then when I turned my cell phone back on it kicked my Roku out again.
I turned off my cell, and I was able to get Roku to open up my YouTube channel again.
Coincidence?
