HI @smiley4hire,

Welcome to the Sonos community. Thanks for reaching out to us about your concern and letting us know what you have done so far.

Let me ask a few questions to help you out with this.

1. Do you get other error messages aside from "Requested Operation Failed"? What's the error message?
2. Is your Amazon Music playlists in the Sonos app match with the playlist on your Amazon Music App/Website?
2. Do you experience the issue with other music services?
4. Have you tried removing and re-adding the Amazon music service on the Sonos app?

Please let us know how you get on with the questions above and then run a diagnostic report from your Sonos system. Kindly include the confirmation number in your response for us to check. If you have any questions about this. We and the community are always here to help.

#4 helps me a lot both playlists and stations saved to favorites quit working when Amazon fiddles something on their end.

If I go back and add the non-working list/station again I end up with two icons, sometimes with slightly different names. One works the other fails.

1. No other msg or code,Just Requested operation failed. Please try again
2. They appear the same to me
3. No other issues with other music services.  Also I have other Amazon playlist that still play with no issues
4. I’ve only tried reauthorizing
