I am facing the same problem and cannot play the same thing across rooms. I added a Sonos Era 100 in my kitchen having previously had a beam + 2 symfonisk bookshelf speakers in my living room. I hope that the problem I am facing is due to teething problems with the new app.

I tried resetting all routers (unplugging, leaving 2 minutes before replugging to power), then the same for the Sonos speakers, followed by force stopping the Sonos app. Since this didn’t work I am not sure what next step to take. I also double checked that the Beam and the Era 100 are using the same mesh access point.

Hey Nick, that seems just like the issue I had. The solution ended up being that the update stopped the auto update of the devices we had on the system, so i would say double check there aren’t any updates that are needed. That fixed our issue. 

Hi Acrouse,

How do I check if any devices need to be updated?

I have the same issue here, but only with my newly added amp. With all other devices (Playbar, One, Play 1, Play 3) groups are working, but not when trying to add the amp to a group.

Updating the older speakers worked for me too. To update the firmware you need to go into settings (the gear button top right). Then next to “Your System” it says “Manage”, then the second bottom option of the first list is “System Updates”. Hope that helps

Yes me too.  An absolute mare.  Mostly comes up with cannot connect, please try again later.  Like anything is going to change!

By far the most flaky app ever.   How Sonos can release this untested pile of poo I don’t know.

So … a multi room player that can’t play multi room!

No work around either.

Same issue here. Play 5 and ERA 300 works fine. But not with Sondbar or Roam. Sonos please fix all these issues.  There has been a lot lately!!!!!

Yes. We had our first get together yesterday using grouped speakers for an extended time. It was a disaster. It was really maddening explaining to folks what was going on. Constant freezes. And when it got going again repeating songs already played. I finally had to give up and played one Move in the middle of the house. It totally sucked. 

I see this is yet another thread they haven't bothered to answer. And calling support which used to useful is a complete waste of time.

Get it together Sonos.

Try ungrouping all rooms then select a different one to start.  I find this works sometimes.  Usually starting with an older device doesn’t work but it’s quite random. 
 

Sonos says this new version is more robust and intuitive.  Er I would say the opposite.  It’s an absolute flaky untested pile of amateur code.
