Hi @MoPac 

Thanks for reporting - I was able to replicate this on my own system and have flagged it for further investigation.

FYI: Removing the account and re-adding it did not help matters.

Hi @MoPac 

My apologies - as it turns out, my testing on a Prime (not Unlimited) account wasn’t the best (I saw a lack of tracks everywhere and mistakenly took that as confirmation, but it’s just Prime being Prime).

My colleague who has an Unlimited account was not able to reproduce your described issue with user-created playlists - could you please verify that your Amazon account is still an Unlimited one? Thanks.

If your account seems in order, please try removing it from Sonos and adding it again:

Remove a music service account from Sonos

Add a music service to Sonos

I hope this helps.
 

@Corry P 

 it is the Unlimited account because I’m able to play Dolby Atmos.

 The playlist Atmos Orchestral Pieces had 683 tracks in it.  I created a new playlist Atmos Orchestral Pieces 2 and moved some tracks from the original playlist to that new one.  Once I got the track count down to 660 or so the tracks showed in the Sonos app.

 I will continue to move tracks until I get the count down below 500 because that seems to be the most that can be loaded into the queue and that’s only if you use Add to End of Queue.  Any other selection only gives you 100 tracks in the queue.

Hi @MoPac 

Understood - thanks for checking.

There is a limit of 500 tracks that can be added to the queue from Amazon Music - it definitely should not be 100 items, but we’re already looking into that.

Did you try removing Amazon Music from your Sonos system?

 Not yet.  I don’t think that will change the queue track limit as it applies to WiiM as well.  So it’s an Amazon issue.  Just wish all the commands in the context menu in the Sonos app gave the same 500 track result.

Hi @MoPac 

I would not expect removing the service to affect how many items can be added to the queue, no, but it may help with your Amazon user-made playlist issue.

 The user-made playlist issue is only the track count which I have enough patience to fix.  Sonos needs to fix the context menu issue described in my last post.

Update:

 Even though I went through the trouble to reduce the size of some of the Amazon Music Unlimited playlists there are some that refuse to show any tracks.  The solution for me was to start the playlist, that showed no tracks, in SonoPhone then miraculously the tracks show in the Sonos app.  $3.99 work around.

 A visual demonstration of the Amazon Music Unlimited user-made playlist issue.  The Atmos Ballet playlist is 410 tracks long so should not have any issues displaying the tracks when opened.  The first screenshot is the Atmos Ballet playlist opened using the 80.x Sonos app.  Result…No tracks.  The second screenshot is that same Atmos Ballet playlist opened using SonoPhone.  Result… Tracks show. 
 

  If I use SonoPhone to start playing the Atmos Ballet playlist it will then show tracks when the Atmos Ballet playlist is opened in the Sonos app.  So to use the Sonos app a third party app is required!!??

 Not sure why, but I did sign out then back into Amazon Music Unlimited.

Hi @MoPac 

Apologies for the delay - I was on holiday.

As we are unable to reproduce this issue in our own testing, and as removing the service and adding again did not help (and also as you are able to load the playlist using a third-party app), I recommend you get in touch with our technical support team so they can document and examine this issue for you.

I hope they are able to help.
