What is going on?   Our bar & restaurant business has been using Sonos for over four years now, with music an essential part of our customers experience.  About a week and a half ago, our Sonos apps updated in the middle of the night, and suddenly our four years worth of carefully curated playlists are totally missing.  We spend our valuable time creating these lists, so that the BPM’s are always upbeat, and fit the lively vibe of our bar.  We cannot allow the generic stations to just play random songs, as these are not even close to the quality of the curated songs we’ve spent years compiling.  Can someone show us how to just download the earlier version of the app?  This new one is so buggy, and jumps around from genre to genre randomly.  It’s terrible, and it’s affecting our business.  Customer service lines are 55 mins plus to try and speak with a representative.  Does anyone know what  is going on?  Any info would be helpful.  Thank you.
