Added a Playbar and Sub to my existing Sonos network last night. Everything went fine as usual, but when making adjustments to the TV and Playbar setting with regards to how they respond to the volume button on my Verizon FiOS remote control, one of the instructions was to go into the Sonos app and adjust the Room Settings. To my surprise when doing so, I discovered that setting is no longer there. After researching online, I learned that the Room Settings option is not available/visible to Sonos users who are in the beta program, and Hat I'd have to leave the beta program and update the software in order to get that option back. So I logged into the Sonos website and left the beta program, but when I tried updating the software, it failed. I tried updating from my PC, my Sonos remote, my iPhone and my iPad and they all failed.
After looking through posts in the Sonos support community, it appears as though this can only be resolved with the help of a Sonos tech.
