S1 app cant add device - stuck telling me to update

If the Play:1 is already running S2 firmware, you need to use the latest Sonos app to setup the device initially, then select the option to downgrade to S1, which should then allow you to add the device to your existing S1 system.

That was not the scenario.  I never got to the point of the S1 controller even finding the new device to know if it was on S2 firmware or not.  It was just stuck in a loop.

Then, it seems the S1 controller was set to update automatically, so overnight the existing Play 1 and Play 3 upgraded so the next morning when I opened the S1 app to play some music, it told me there were now zero compatible devices and I had to use the S2 app.  The night before I had been using the S1 app and playing on the 2 speakers, no issues.

I’m now on S2 with both original speakers and that let me add the 3rd speaker after having to hardwire it to the switch and updating it.  But a new problem has emerged where choosing “Everywhere” will only play the music on 1 device or another but not actually “everywhere”.  You can see that the app thinks it is playing everywhere as the sound bars go up and down but music actually only comes out some but not all the rooms.  I can change which room gets music by selecting it individually but when I change to “everywhere” the music never comes out the other speakers.

current setup

Play1 + Play 1 set as left and right pair called Living Room

Play 3 set as Kitchen

playing music everywhere will only play in one room, not both
