Cannot sign into Apple TV+ on my new TV (Sony Bravia)
We recently upgraded our TV, now owning a Sony Bravia x90j with Google TV. Setting up the new TV has worked like a charm with the singular exception of the Apple TV+ app. We have utterly failed to sign into our Apple TV+ account on the new TV. The app gives us two choices, go to the tv.apple.com web site or enter credentials using the remote. Neither works.
When we go to a browser (on phone, on tablet, on laptop) and log into tv.apple.com… nothing happens. The app on the TV does not sign in and I see nothing in the web page that tells me to authenticate a new device (or how to authenticate a new device).
We we try to sign in on the TV directly, we enter our credentials, the app thinks for a few seconds, and the app then tells us that there is an error and asks us to try again later. We've been trying for three days now with no luck.
Apple, can you give us a hint for how to sign into the app on the new TV? TIA
