The unability to create the personal music library in searches is bad enough and has been reported by many users already.
Now I faced another challenge when trying to browse the music library: so far, in the new app, the listing of albums was accurate, still a bit clumsy to go through without the A-Z bar on the side, but possible.
On the weekend, without having done any further app update (Android), the album list looks very different. The Sonos app lists every song of an album as one album (!), so the actual list of albums is not there anymore. With 55.000 titles on my NAS, it has now become completely impossible to choose albums or tracks.
Have other users also run into that problem?
