When Sonos ‘upgraded’ its app, I pretty much lost everything.  I have a large music collection and I prefer to keep it on my MacBook where there is enough storage for it.  When the ‘upgrade’ occurred, I had already spent HOURS getting the app working again after an automatic update happened sometime in January while I was away.  I returned home and none of the 8 speakers matched their labels anymore, songs would not play completely and music bounced from one speaker to another.  When I called Sonos, one rep told me I should not have set the updates to automatic.  Another one altered my email so the remedy didn’t get to me for several weeks--after I wrote a snail mail letter to the CEO.  I have now moved away from the Sonos app and am just using Apple AirPlay.  Is anyone else going this route?  I don’t have many of the issues I was having with Sonos.
