I made a few changes to the post from Kenneth this morning with some more details. We're starting to see playback coming back after a concerted effort from both Spotify and Sonos teams. It's a little early to give you an all clear, but feel free to check Spotify to see if it's working again on your systems.
Thanks for all the diagnostics you guys posted, they're very helpful for the team to identify issues such as this. We’ll let you know when we have an official resolution for all systems.

Although we will both conduct a more thorough engineering review and investigation over the next few days, we suspect at this moment that today's service interruption was caused by a latent incompatibility in how Sonos players interface with Spotify, and triggered by a routine service update to Spotify's architecture. Neither partner had reason to believe that this update would create problems for our customers, and both teams accept responsibility for today's disruption to your home listening.
After we verify these results through an investigation, we will ensure that this latent problem is addressed so that future updates do not put your listening in jeopardy. Please accept our sincere apologies.
