Music app apple tv 4 asks me to log in when I'm already logged in

After last iOS update on ATV 4, the music app has behaved irregular. it is just on random it allows me access, to use it. most of the time I'm asked to log in with my appleID, and then it just hangs. The thing is, I AM logged in already.... I should not be asked to log in....

It does not help to log out from icloud or other places. I HAVE TRIED, TO THE TIRESOME BEYOND AND INFINITY.

Clock and Timezone is correct, I have Internet connection. Every app is updated. I even tried to reset the hole **** thing, but that didnt work at all. it would not start resetting....!!!

Any ideas?
