S1 app won't work anymore

Same on any 7th Gen Fire Tablets. No way to upgrade the tablet past 5.6.6.  

Totally useless … was a great controller :-(

I’m having a similar problem just downloaded the S1 update in my Mac and is not seeing most of my devices. My iPhone got updated automatically and same issue. I’ve read some other thread with similar problems . 

Surely the only solution cannot be to get a newer phone? 

Everything was working yesterday, there must be a way to put an app that works on Android 6?

This isn't a rant against Sonos,  merely a question on how I put the app on my phone 

see this article.  You need Android 7 or later to be able to run ether S1 or S2.

You might be able to download the older APK and run it with limited functionality, but i haven’t tried that yet. 

Works with the same limited abilities as it did before on three of my devices.

i can’t get it to work at all on one of my 7th Gen Fire tablets.  tried an older SDK with same issue.  Even though their web says what you found…. that it should still work with limited capabilities. 

@ninjabob , did you update to the new S1 release, or running earlier version?

So the question for Sonos is which app versions will work with a system that has been upgraded to S1? Knowing this will help those who are not on S1 decide if they should update to S1

How do I upload the version pre-S1 please?

Sonos do not provide any means to role back the version of the software used by the speakers.

They also do not support rolling back the controller app, however .. There are third party web sites that keep previous versions of apps and some of these have previous versions of the sonos controller app, a search for previous versions an android apps will provide information for Android for example. As these are not official Google or Apple sites you go down this road at your own risk.

I "upgraded" to S1 using the Desktop PC App which in turn upgraded all the speakers to S1. I then uninstalled the App and reinstalled the App one by one on each of my Android Controllers from the Play Store. The Samsung S7 Edge shows the App as S1. All other controllers showed the usual "this version of Android ........" warning but worked as limited controllers as before. These controllers just have the icon Sonos. I can run S2 as all my units comply but don't want to lose my "old" controller useability and don't see any advantage in running S2. I have now turned off Auto Updates and blocked update.sonos.com and update-firmware.sonos.com in my routers firewall to control further updates until I am sure my equipment will continue to work as it does now.
