This issue has been posted several times on here by various users, and no real answer / solution has been provided yet — so let’s try one more time!
I’ve had this issue for around 6 months now, started as soon as I switched back to Apple Music from Tidal.
The Problem: Certain views of “My Music” cannot be accessed in the Sonos controller app. For me, the issue is isolated to “Apple Music → My Music → Artists” and “Apple Music → My Music → Albums”. The precise error message is “We’ve run into a problem. Try again.”
SONOS TEAM: this is NOT a wifi issue, and I’ve already gone through the obvious troubleshooting steps (all the way down to a complete factory reset across every speaker and set the system up again from scratch). I’m a technology architect, I deal with issues like this everyday. This is a software bug that needs to be raised with the appropriate product manager. The fact that Playlists and the Songs are both working perfectly fine makes this glaringly clear to anyone familiar with the Apple Music API that there is bug in the code specific to the Artists and Album routes. This is not likely to be an account issue or a broad authentication issue, since every song in my account can be returned perfectly fine under “Apple Music → My Music → Songs”. Happy to get into more detail with the PM if you want to have them reach out to me.
Here’s a diagnostic, but I doubt it’s going to help: 1764099374
Really hoping we can get this solved this time!
