Gmail with Apple tv 4k device
I'm receiving an 'Unable to log in' error when trying log into my new Apple tv 4k device using my gmail account associated with my appleid. However it shows up as one of 'My Devices' when I am logged into my account on apple.com. I do not own any other apple products so I am attempting to log in manually. My appleid and password are both correct. I've tried multiple times to log in. Please help if you can and point me in the right direction to resolve.
Apple TV 4K, tvOS 16
