I order my music library into four folders corresponding to broad categories, each of which contains many sub-folders. Each of the four is a “Sonos favourite”. This convenient way of navigating the library continues to work in the desktop app, but in the new IPad app, under each of these favourites is the message: “No longer available. Press Edit Home to delete”.

Will this way of organising a music library once again become possible, and if so, roughly when?
