'Sorry there was a problem with apple music'
When I ask my HomePod to "hey siri, play some music." it replies "here is some music just for you" then there is a silence before it times out and replies 'Sorry there was a problem with apple music'.
The problem is intermittent and is temporarily fixed by removing the device from Home App and then re-installing it, but then the problem comes back randomly minutes, hours or days later.
Sometimes the problem goes away by itself for a little while.
The device is connected to the Internet because queries for "What's the weather like?" always succeed.
My HomePod Mini's don't seem to be affected.
Any ideas?
