I’m flabbergasted that the v80 app was foisted on the world as a less-than-beta product. Beyond being unable to search my music library and add music to the queue (arguably the main functionality of any Sonos system?!?), the absolute basics aren’t working for me.

• Playing music: Any time I try to group any number of speakers something fails. I’m talking two rooms. Two. One will mmmmmaybe work for a little while, then the other one will come in but the first one will cut out, then who knows? God forbid I try to group four or five rooms, no chance. Please fix this first. If I can’t control multiple rooms with the app I might as well use a bluetooth speaker or maybe a good old cassette boom box.
• The volume sliders: I’m not even sure how to describe this. You change the volume, then it snaps back to the original volume but then slides itself forward – some – then jerks around a bit. Meanwhile, on my speakers, some room’s volumes change a little, but certainly not what I asked them to change to. Then the haptic feedback on it? I guess I appreciate the little massage I get from changing the volume. 
• Music library: Beyond not being able to search my library (baaaa huh?), it doesn’t even show up on the home screen Mo’st of the time. Then, as I can’t search it, I have to browse it. Gone are the first-letter guides down the side, and the lazy-loading means the scrollbar is inaccurate, aaaaaand my otherwise not-super-huge music library is more or less useless. Only way I can really find anything is to use another management app, create a playlist called “Sonos sucks,” or similar, add what I want to it, then find it back in Sonos (if and when my Music library shows up)
• Usability: Everything is a pull-up sheet now? At one point I somehow had four pull-up sheets on top of each other and the only way to get back to the main screen was to push them all down. Find a song or an album and want to add it to the queue? Oh, wait, you can’t, but even if you want to replace the queue, tap the ellipsis button and get another slide-up sheet that has only one option on it? Why? One sheet after another after another. Trying to find anything is difficult and without a functioning search it’s impossible to really find.

Nutshell, why? What was the old app NOT doing for anyone that the new app is? All I see is missing and broken features, downgrade after downgrade, horrible UI/UX, and, most egregiously, speakers that won’t play music properly anymore. 

You already had to split of S1/S2, maybe provide us the opportunity to stick with S2 instead of whatever ‘S’ this version is. I didn’t add any new speakers, I’m not asking for any new features, just want to be able to control music in multiple rooms and that fails miserably.
