I have removed some Artists from my Apple Music account but they are still appearing in Apple Music - My Music - Artists/Albums on my Sonos Controller. The Songs have gone but the Artist and Albums are still there. If I try to display the contents of one of these Albums, 'Unable to browse music is displayed'. I have the issue on PC, Mac and iOS devices. Any advise on how to remove these deleted Artists & Albums would be appreciated. Thanks. Paul.
