It is awful. Volume control from app takes seconds for a

change to take place, queues don’t show all

songs that are tee’d up, controls for track advance sporadically work, and changing back to TV source took 3

minutes and MANY tries. I spent thousands on my set up, and can’t even use it.  I used to sing the praises of Sonos, but no longer.  Fix this.   Not sure about everyone else, but if it goes on for too long, I’ll change it all out.  It needs to work. 
 

FYI:  Running app on iOS from my iPhone 15 Pro Max.
