So I joined the Google advanced security program and it logs you out of every device your account is connected to which would be fine, but google TV does not work at all without an account signed in. No Netflix, Hulu nothing... And I tried wiping the whole thing and setting up using google home (iOS) based on an article I found which seemed like it was working (I signed in with my phone and security key), but it said it was unable to link my account. Does anyone know a fix? I know some platforms are not allowed if they don't meet the security standards, but It seems quite odd that google would brick their own product. It seems like this issue is open and locked with no solution....

SOLVED: I think what happened Is that I had not removed the device from the home app after the reset. Once you reset AND go into the app and remove the device from your “home” you can start the setup from a completely clean slate and I was able to link my account successfully.
