Sonos update ruined my tv connection

I did contact support and after an hour of unuseful support, I kept playing around with the app and made it work, at least for one day.  The next day it was down again.  Another hour of “playing around “ and I think I’ve sort of figured out how to keep it working until it doesn’t.  The point of my question was why did I have to spend several hours with my trial and error approach when I had a system that was already working and has been working for a couple of years?  I didn’t need an update, especially one that changed things so drastically that it wasn’t obvious what to do to make it all work again.  Surely the design team must have tested it first with some beta volunteers. . . or did they just test it within their own “expert group” ignoring the problems an average user might have?  I have a day job and work many hours.  I didn’t enjoy coming home after a long day and have to struggle with the Sonos (and my wife didn’t appreciate it either).  I spent good money for the Sonos system and spent the requisite time setting it properly the first time.  I didn’t expect to have to do it again.  Had I known that, I never would have purchased it in the first place.  There was not even a heads up that a significant change was coming or any instructions on how to deal with the changes.  Don’t blame us.  Sonos is to blame for this one.
