Sorry, there’s problem with Apple Music

This is recurring after not being an issue. It’s happening primarily when I ask Siri to play on my HomePods, a stereo pair with a 4KAppleTv. Support had me ungroup and regroup the pair before. That doesn’t work now. It’s only happened since the fix for HomePod Minis was pushed to AppleTV OS update to make them the primary output, as that is the setup in another room.
