Has anyone else had this problem?

About two months ago I opened up my Sonos interface (Desktop, iOS, Android, same results accross all devices) and my myriad of Spotify playlists which had been meticulously sorted into sub-folders by genre/mood/etc are now unsorted into one giant list.  Also, my "Starred" list (I know I know I know... Spotify is trying to kill the Starred list... harummph) is unsorted and doesn't contain any of the tracks I've added since August of 2014.  I've tried disconnecting my Spotify account and reconnecting... nada.

I've raised this issue with Sonos several times only to get no response (which is very strange, they are normally quite quick with at least a response, if not a fix).  I'm wondering if the reason is because it's fundamentally a Spotify issue and not a Sonos issue?   

I've been a Spotify/Sonos lover for a long time but this is starting to kill my buzz.  Sadly, if this doesn't get fixed soon, once Apple Music is Sonos integrated, I might be making the switch.  I've already invested in my home music hardware... that can't be changed.  By my music service is month-to-month.  I can switch that any time I want.

And if anyone from Sonos is reading this... WHY HAVEN'T YOU RESPONDED TO MY PLEAS?????

Thanks, everyone.
