Which way do you try starting some music? Via Sonos App, Amazon App or (as your error message sounds like) via Alexa voice assistant?

If it’s Alexa, do you use your Move in a S1 system? There is a current problem with Alexa on S1. 

Hi @NeilMcCallum 

Welcome to the Sonos Community!

Sorry to hear of the issues you are having trying to play Amazon music to your Move. If you are not using the older S1 software, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.

I hope this helps.

I have used my Sonos devices for a long time.  I gave up trying to listen to Amazon Music years ago.  I kept having to recertify the Amazon connection so frequently I stopped using it.   I use Pandora and iHeartRadio without issue.  I am not sure who to point the finger at but it just gets old.  I can play Amazon Music on all my mobile devices without issue.  I lost count on adding/deleting the Amazon account from my Sonos subscriptions.  It works for a while and then stops.  If I recertify it it will work again.  It’s like banging my head against a wall 🤪

Hopefully this will get resolved at some point but I have not been successful at finding a solution
