Just wanted to add to conversation on problems of new app for people with a home digital library. Since update lost much functionality, at first ability to see library , this is back but when added new disc to my library hot major problems , multiple copies of albums with no content or single track , most of library has disappeared or is damaged , no a-z listings of albums . Limited functionality compared to old S2 . At present until current problem is fixed have limited or no use of system . I was a big fan of Sonos with old app now my investment in their speakers is lost . Please bring back old S2 app for people with digital home library. I don’t want your hi tec speakers or to stream everything, Just want to be able to listen to my extensive classical music library. Sonos please fix this fast to give us back what had before May !!!!!!
