Dear Sonos Customers,
Please be advised there is a problem with the Sonos Controller for Mac when using the Deezer Music Service. Selecting "My Smartradio Stations" or selecting Artists from "My Deezer Library" may cause the Sonos Controller for Mac to hang indefinitely requiring the user to Force Quit the Sonos application.
Sonos is working on a fix to this issue as quickly as possible and we apologize for any inconvenience.
