I emailed Sonos with details of an error at the weekend - got a message promising a reply within 24 hours but have heard nothing - so though I would try here.
In the past few week Spotify (Premium Family members) has become completely redundant on our Sonos system. None of us are able to play any Spotify tracks on Sonos - either from the Spotify app or from the Sonos Controller app.
We have been through all of the suggestions (rebooting, removing Sonos, removing Spotify, checking Wi-Fi connection etc) and nothing has fixed it.
We can stream from our Music Library to all devices (so we assume wi-fi is working fine ) and we can stream internet radio stations (so we assume Sonos has internet connection).
I have submitted support diagnostics reference 1445143747.
Any suggestions much appreciated
