S1 S2 I don't want to upgrade

...and this is what's under "more options"

Spikely you are a star. Those are precisely the screens I show! Please Sonos, tell us how to get back to our system! I can use the speakers because they are already linked to Alexa. But I can't adjust anything!  

Sonos is going down if this continues...

@DrVJMJ, I already told you what to do.

Is this process reversible?

While we don’t recommend downgrading your products to S1 after updating to S2, it is possible to downgrade by resetting the S2 products to their factory settings and adding them to an existing S1 system. An existing Sonos product running S1 software is required to downgrade an S2 product back to S1. Note that all settings and preferences will be lost when downgrading a product from S2 to S1.

According to your profile all of your units are S2 compatible, and if you’ve “accidentally” upgraded to S2, then there’s nothing you can do about. Uninstall the S1 app, download the S2 app from the store (connect to an existing system) and provide the screenshot I have been asking for.

Firstly click “About my system” and share the response, as Smilja has requested. This will let use see which devices you have and what they are running.

What happens if you just click Done on that final screenshot?

"Done" simply closes the menu. I've listed my devices above.

No, you didn’t. I’ll need to verify on which firmware each of your Sonos players is running on. Uninstall the S1 app, download the S2 app from the store (connect to an existing system) and provide the screenshot I have repeatedly been asking for.

Or give Sonos support a call next week.

Hi Simon - can you address this thread re: the S1 app trying to force us to upgrade the controller on systems that should not require it according to Sonos documentation? A few of us are being blocked by it, and it may be easier to address here than more of us contacting Support for the same issue. Thank you!

Here's what's running on the speakers. We do not want to download the S2 app given all the problems reported - that's the whole point of this thread. I only have 6 speakers, not 13 like someone else on another thread is now struggling with trying to re-set up again, but I still don't want to go down that path if I can help it...

The screenshot does clearly say that the Play:1 is on firmware S2 (12.0.1). If the other Sonos devices also display S2 (12.0.1) there is no way back and you are required to delete the S1 app in order to use the S2 app. You can’t operate the system if there is a version mismatch between controller app and speaker’s firmware.

*$&÷**j#h.

Ok thanks - they must've auto-updated overnight, since there was no warning or anything btwn the time I went to bed around 3 in the morning and waking up to this app screen. I still may limp along using voice commands and manually adjusting volume to see if Sonos sorts out some of the kinks with this app/OS upgrade.
