As a follow up to the Patrick Spence q+a on Reddit, Sonos posted a Google Form that you can use to submit an issue you are having with your system. Sonos will allegedly follow up with you.
Here’s your chance to avoid the dreaded support wait time and possibly get your issue looked at. Form will expire in approx 19 hours. Go go go.
