I think the current title is mistaken, the twitter user isn't claiming he can't use the Apple TV, he's just saying the message appears.
I encountered the same message when iOS 16 had just released and wasn't available on my iPad yet. It wasn't a blocking message, pressing "OK" was enough to make it go away, and when iPadOS 16 finally came out I was able to clear it.
It's bad UX but the Apple TV can still be used as before.
