Some Apps on Apple TV 4K won't work after a period of time

I have an Apple TV 4K (previous generation).

At start all is well and working fine, but after let's say one hour watching HBO or Prime or Netflix and switching to Apple Music or YouTube the App opens well, navigation is good but no song or no video starts playing.

This can only be solved by restarting the Apple TV. I do not think this is the way forward.

I had this problem one year ago and after contacting the Apple Support, the advice was to create an alternative user. And for a while it worked but the issue is coming back.

I am on the latest version of the OS.

Any thoughts?

Kind regards

Gilbert
