Worth adding too that just like @benzgrant I get the same error using the official web player, and it also occurs when loading the list of library artists, but not songs or playlists. Requesting the library artists returns { "errors": [ { "id": "OVBAPGJPXEC6DUKGRJSEHIFG3Q", "title": "Upstream Service Error", "detail": "Error fetching library content", "status": "500", "code": "50001" } ] }

This seems to have still not be resolved. Has there been any progress at all on this issue?

I have the EXACT same issue with my own account. Interested to see if this goes anywhere...
