Amazon music playlist errors [C10001] and [C7 - SC1300] on Bose Music app Soundbar 700
I have a customized playlist on Amazon Music. It's 604 songs long. It plays fine through the Soundbar 700 using Alexa ("Alexa shuffle playlist X on Amazon Music").
However, using the Bose Music app, I cannot view or play this playlist.
When I attempt to view it from the Amazon Music->My Music->Playlists page, I get a red error message bar at the top of the application that says "Something went wrong [C10001]" - and nothing else happens.
When I try and play it from the same screen, after a short pause of a few seconds, then I get a full screen error message which says "Oops. We can't connect to that music service right now. Please try again later. [C7 - SC1300]". Clicking OK takes me back to the previous screen, but now the bottom bar says "Speaker's Ready. Please select something to play"
I have been able to find a workaround - that is to split to playlist into 2. Each of these can then be viewed or played successfully. It also seems that the maximum size of a playlist is 326 songs. At that number there are no problems, but larger than that and the 2 errors above occur.
Any advice? I've already removed the Amazon Music service from the Bose Music app and reconnected it. That didn't make a difference.
