Apple Music Interruptions on iPhone and Smart TV

Hi Community

My Apple Music interrupts lately, without knowing exactly when this started. At first I taught it was only happening when playing from the app on the smart tv. Now it seems as well happening with the app on the iPhone ... sounds (and song) stops regularly and sudden plays again, repeatedly.

Tried deleting the app and replace it. All upgrades seem up to date.

Probably a common problem with an easy solution :) ? ...
