I have had Sonos for a decade.  4 amps, a sub, multiple Play:1’s, Play 3, 

It went from one of my favorite products … so intuitive, so easy.  After all the upgrades, the app is impossible to use, the speakers for my tv work for 10 seconds then stop working for 3 seconds.  If I didn’t have so much invested in the system, I’d throw it out.  DO NOT BUY ANY SONOS PRODUCT UNTIL IT IS FIXED.
