I just wished I consulted the Community BEFORE upgrading to the NEW app (which I would have postponed until the SONOS dev came back to reality...). I am all for changes, fixes and new features (fixes and new features, in that order and not new features over fixes… spend time fixing existing problems before throwing more features into the mix).
When comparing moving from Sonos S1 to S2, THIS upgrade is a disaster (it did cross my mind that SONOS pushed the BETA version of the apps instead of the final tested version...). What happend to the TuneIN stations preset, art covers, alarm set-up? The email we all received about 2 weeks ago did not mentionned any of this for existing users. I just hope SONOS will react to all the comments about this upgrade and provide a way to return to the previous version, until the new version is acceptable.
