Apple TV+ no longer working on Apple TV

Oooooook. Might have found a solutions.

Background:

I've been logging in and out of my different accounts (different countries, different apps) on my AppleTV.

Ran into the same problem as above.

Solution (for me):

Log out of the "Store" account which you find under Settings > User & Accounts > Default User > Store.

Then log back in.

That solved this for me.

Same here.

In Japan.

"This video can't be played because you don't have access to it or it's no longer available." on the AppleTV, but works fine on phone and laptop (using same account, ID and for purchases).

Started today, January 4th.

tvOS 18.2

Use the Apple 4K box, might fix.

Yep! This did the trick! Thanks
