I’ve been a Sonos owner for since 2015. I have 15 Sonos devices in my Sonos system consisting of Play:1, Play:3, Connect, Sub, Playbar. The system worked beautifully. I always bragged about my awesome Sonos system. Then I "upgraded" to Sonos S2. What a mistake. My awesome Sonos system has been rendered almost unusable. I don’t really want to spend hours troubleshooting a system that worked perfectly before I upgraded. How can I downgrade back to Sonos S1 if I have upgraded all my devices? Thanks for the help.
