Sonos System can‘t be found by new app

What a joke, has anything been done about this issue, I’m having the same issue since the app update, total joke, cannot use the system!!!!

No nothing 

Your firmware may indeed be too far out of date to update via wireless.  Try connecting it to your router with an Ethernet cable and adding it again.  After it updates, you can disconnect the Ethernet cable and deploy it wirelessly. 

I have the same issue - app not finding g my system.  I see there are many (all?) with the same experience.  This is a piss-poor service from a company that used to pride itself on customer service.  
what are you doing about it - or do you genuinely not care????!!

Still can't find my system and I've tried the updating network settings but can only find my beam and sub, not my play: 1 surrounds. Pretty absurd a hot fix or rollback of the app update STILL hasn't been done.

Same problem. I spend hours trying to reconnect the system (Playbar, Sub, 2x Play1; symfonisk; play1). Once I connect one speaker and try to connect another I lost the system again and again. Can’t discover plugged in and reset speakers, can't find system in my networks, app is telling me to log in as owner even when I’m logged in. For weeks now I have useless speakers around the house. Is there any update on when this core issue is fixed? I cna only see some features listed but I can't even get the system to work so why I care about extra features… 

What’s interesting that this total issue exist with my parents system. I have other Sonos sytem in my home and here I have one new Era speaker and no issues with the app or losing the system. I suspect Era must link the older speakers with the updated structure. However it worries me that I invested in system that's worthless once company decides to make an software update.

Disgraceful service and total

disregard for customer experience.

I find it hard to believe that Sonos hasn't fixed this after a month of complaints.  And no public statement (that I could find)?  
 

The new version of the app doesn't find my system at all - it just asks me to sign in over and over and over and over.  I've never seen a mature company break something so badly.  

Confirmed Workaround here :

None of my apps (Android, IPhone, iPad) would find the Sonos products anymore. And they still don’t. 

But for me, I can still control my Sonos by logging in at play.sonos.com (on a laptop). That web app can see my system and let me control music. So at least things work in the meantime till they get the app sorted.

Hope it works for you all too.

Experienced the same thing, the whole system was gone from my Sonos iPhone app, but my iPad still saw the system though unable to sync the music from one room to the other.  Called Sonos Support, and provided them with diagnostic code, support saw that the amp was missing an update, so did that.  Restarted my WIFI router, saw the option to join existing system became available, joined it, and now back in business.
