@JoeKun Works perfectly now, thank you! Can I ask what the change was, in case I encounter this again (other users etc)? Might help others get the fix quicker if I can let them know the cause. Thanks

Oh strange... I wonder if it's a regional rollout of a backend update? I'm in the UK and still getting the exact same issue. Unless you did something to your library I can't see why this would be the case... Curious.

Hi @JoeKun, The only information I get back from the error is { "errors": [ { "id": "QPYHSMMBQU2MSHVNUADDCRUP5M", "title": "Upstream Service Error", "detail": "Error fetching library content", "status": "500", "code": "50001" } ] } returned when fetching the list of albums in the users library. This seems to be really account-specific. It occurs on my personal account, but seems to be really uncommon.
