Apple Music signs you out and says that there's a problem with the network even though everything else is functioning properly (like: YouTube, Facebook)

Hi,

This is Mahbubur Rahman and I am asking this question on behalf of a friend of mine. He uses Apple music on his android device.

The app worked fine so far but recently, it's been pretending that there's no internet connection. It logs him out and whenever he logs in, it later says that there has been a problem with the connection. Every other app works perfectly fine tho.

He showed me his phone, I reset his wifi, restarted the phone, cleared the cache but nothing seems to solve the problem.

Let me know what can solve this problem, he's getting frustrated without music now haha. Thanks.
