That said I do dislike the new app rollout.
I do feel like there has been 500ms to 2 seconds of added lag in certain actions. I can't quite place what's going on though. Not enough to be a deal breaker yet.
I feel the surround sound experience has been very hit or miss but can't tell if it's Sonos or the media platform I'm watching videos on.
Originally they said the feature was totally supported but just didn't make the cut for the initial app release. I've heard that story before, including from my own PMs. Can't say I'm too surprised that the feature still isn't supported and I've yet to see any further mention of adding it back.
That having been said, I've been a longtime Sonos customer and have loved the experience until this disaster. Unlike other commenters in this thread, my family has loved the ease of use and ability to move music between rooms and add / remove speakers. We also have our record player hooked-up with the Sonos Bridge. I don't want to run a server, and it would be an absolute nightmare to hardwire my house. I hope they get it figured out, I'm not throwing away my speakers but it'll be years before I make a new Sonos purchase (if ever).
I live in a small place and only have a couple original Sonos 1's. Even then we usually only have one playing. I'm just going to sell both and get a similarly small speaker with an Aux input, it'd be just as convenient for me to plug in a phone and stream music from either Spotify or our home server.
