Serious s/w issues @Sonos. Update your controller and knock every speaker off network and can't get them back. This will undoubtedly take me a couple of hours to fix AGAIN. Last update did the same thing. You need to do better.
After controller update completes, speakers initially showing green light. If rebooted by power cycle they come back white light but not seen by controller. Suggestions on how to get speakers recognized by controller appreciated.
