Adding my name to the many others who feel the new app is a step backwards.
it’s unstable and often unresponsive. Hard to switch speakers on and off, volume often unresponsive. The app often does not connect except with a 5 minute delay.
I love my speakers and setup, I have owned various Sonos systems in different homes since 2006. They have worked really well until now. Please fix it before my wife tears the whole thing out!!!
