Are you referring to Sonos playlists?

  My issue is with local library artwork not showing in Sonos playlists.  Two of the three Sonos playlists ( 1st screenshot ) show no artwork because the first tracks are from my local library.  Oddly though when I open “Cello Concertos” those first local library tracks do have artwork ( 2nd screenshot ).  But if I put “Cello Concertos” in the queue the artwork is not shown ( 3rd screenshot ).  The “Jazz” playlist in the screenshot shows artwork because the first tracks are from Qobuz.  That artwork shows under all conditions.

 If you’re referring to your library playlist artwork then my library playlists reflect what you describe; track art is there, but large art is missing.

 My biggest complaint is when you load a local library playlist or any Local library tracks into the queue there is no artwork showing.

Read the above with interest... 

Android 80.09.04 

I can see about 20% of my playlists created under Sonos Playlists (which appear under Sonos Favorites - all Amazon albums- along with Recents Artists from those Amazon albums) but no album art, all placeholders. However, I created a new playlist yesterday from Amazon and it was complete in both a large placeholder, album art and thumbnails interestingly. So some background advances... but a way to go. 

Still await the functionality we have on the Windows/pc 16.3 version, viz;

Full Sonos Playlists (most from own library) 

Album Art for Subscription Headers and library

Correct dating on podcasts

Icons to denote hd/hi - res on library tracks

But most of all... full editing... 

Saw youtube post by CEO 2nd Oct with full mea culpa, presumably as in early May the roadmap mentioned library restoration by Sept…

​​​​​​Interesting that iOS version is moving quicker...

Artwork stored on a NAS-type device cannot be displayed in the Android app, because a Sonos engineer forgot that modern Android forbids http connections, and that is how NAS artwork is read by the app (via the speakers).

There are work-arounds for this Android block, but the work-around was left behind in the old app along with so many other useful pieces of code.

 I’m using IOS and in some areas on the new app the NAS library Album Art is seen and in other areas of the app it’s missing.  That’s a Sonos issue.

 Don’t have an Android device, but it sounds like there is no Album Art from a NAS library shown anywhere in the new app on Android.  Is this the case?

Yes, Android is 100% broken for that.
