I have two homes.  At primary home the new controller is absolutely horrible,  Can’t change rooms, won’t allow real access to Idagio ( Classical music stream) will not allow toggling between phone and I-pad and takes multiple attempts to stop music.  Went to my other house with older components only compatible with S1 and, Oh my gosh everything works seamlessly and quickly.  Switch from phone to I-Pad and access all streaming.  Oh my how nice that SONOS can work again.  Fire the developers of the new controller tomorrow.  Absolutely horrendous.
