I’ve noticed an issue with Sonos seemingly unable to actually switch between multiple Apple Music accounts. My wife and I each have an Apple Music account, each linked to our home Sonos system.
I first noticed that Apple Music through the Sonos app only shows my wife’s playlists (Apple Music —> My Music —> Playlists). This happens regardless of which account is selected on the first Apple Music screen. It does not change when I restart the app or my iOS device, or when I cycle through Apple Music accounts.
It’s also showing in the other Apple Music menus like “For You” and “New.”
In short, although the screen shows that the Apple Music account has been switched, and there’s a momentary screen refresh like it’s loading, the content displayed does not change.
