Corry P confirmed that Sonos are controlling the release of this function so although you have the latest versions of app and OS you may still not see the new features.  (this is different to the way Android PlayStore and IOS AppStore often stagger the release of App Updates over a few days,

No info yet on exactly what data they are using to control this; might be region or ranges of IP’s, or Sonos id’s etc. they haven’t said  

nor have they indicated how long it might take   I have had the latest new versions for nearly a week now and still no sign of the features appearing 

I am using the Windows Desktop controller which retained the create / edit playlist feature throughout this new APP saga (May 2024).

I did note that in this latest Android version (and the Ipad version) the Album Art is not displaying in the Queue view.  (whereas it was previously) 

Thanks for the update, apricated
