apple music (buffering?)

For the last two-three months i am experiencing issues with apple music.

while playing songs that are being streamed (not local on my device) i get something like buffering issues.

the song stops for 5-10 sec and continues, making listening to Apple Music impossible.

it happens on my Iphone xs max and on my appleTV 4K, bot with latest iOS.

(all the apple products have)

i do not have any streaming issues with other companies such as youtube, Netflix, facebook, AppleTV+

everything works fine there.

only with Apple music (any song)

What can i do to resolve this issue?

Thanks,.
