Apple TV making me log in every time i use it

Every time I got to Apple TV, I get the screen requiring me to fish out my phone and log in. I get signed in, all is well,and then the next time I use the app it does it again.

This started in the last two weeks, but already it’s so irritating that I’ve pretty much stopped watching Apple TV. The TV is a Hisense, and both the TV and the app are updated to the latest available versions. Other apps are functioning as normal.

I checked for previous threads on this topic and it seems to keep coming up, but doesn’t seem to get an effective solution.
