From 4 to 2 stars. The new version is just not complete. A lot of functions is no longer available, 50% of the times it won't turn up or down for a group volume, but just one room. Very slow to connect other rooms, and extremely slow to change songs.
Slow to connect to other rooms, and I could go on with mistakes.
All in all it is a downgrade rather than a update. Why would sonos be this clumsy and release this app?
