ARe you using the Amazon music in the Sonos app or is this playing Amazon music via Alexa.

Also what country are you located?

Using Amazon Music on the Sonos App

I guess first thing I would check is go into Alexa app … go to devices and chose the Arc.

Assume  speaker syas Built-In

Device location and Time zone correct

Aslo under the bottom right more option Music and Podscasts.   Shows family servie Amazon Music and Amazon Music is under the first line and set for playing music too.,

I dont have Alexa app. This is only on the Sonos app

So are you trying to play Amazon music via the Sonos App?

Then I would probably check address in your sonos account.   What country are you?  Have you moved countries?

@cjeffaree, Is it Prime Music you are trying to play music from? As of Nov. 1 Prime Music is basically a customised radio station. It’s no longer possible to play an album in correct order, trying it results in “connection lost”.

Examine the new Amazon Music app. Here’s an official announcement.

Yes its Prime Music im trying to play from. @Smilja this seems to be the answer, many thanks. Very very sneaky of Amazon. I never saw any notice of this change at all.

Yeah Amazon and Sonos have NEVER played well together - often times Amazon would reset the links to playlists and favorite stations in your Sonos Favorites.  Now Amazon is playing fast and silly with its subscribers with this NEW and WORSE new service that actually removes features.  I blame AMZ and not Sonos for this recent mess.
