We are reaching out to our customers in regards to a recent update Sonos rolled out in early December, 2016. Sonos software release 7.0 included some improvements that Spotify has made to the music experience on Sonos that has resulted in better reliability and will ensure the best listening experience moving forward. These improvements include the exciting launch of full control of Sonos from the Spotify app.
The majority of Sonos owners who use Spotify have already successfully updated their system to 7.0 or higher. However, we wanted to give you a heads-up that beginning February 28th, 2017, Spotify users on Sonos who do not update to the latest Sonos software 7.0 or higher will no longer be able to use Spotify on their Sonos. This change could impact any unauthorized Sonos integrations in terms of Spotify functioning on those systems. Endorsed partner integrations that have updated to Sonos software 7.0 or higher will not be impacted.Any Sonos owner who has already updated their system to Sonos software 7.0 or higher is not impacted by this, but we wanted to communicate with you in advance so you can help all of your customers update to the latest Sonos software to ensure they can continue enjoy listening to Spotify on their Sonos.
Here is a link to the full release notes of Sonos software 7.0
Thanks-
Doug
