Where is the music index now option and the new S2 app?

I made the mistake up upgrading the app on my iPhone to the latest 80.00.04. I have lost access to my two Play 1 speaker, two Play 3 speakers and to my own music library on a NAS drive. I have re-installed the app, reset one of the Play 3 speakers and it lets me add the speaker but I can’t select it or use it so I now have a Sonos system that I paid a lot of money for but is now useless! Why don”t Sonos updates come with a regression option?!!! Would not recommend Sonos to anyone!

I don't know nor understand Android updates, but after downgrading my Sonos app to v 16.1, ie the 'brown app', this was yesterday, so today i made the stupid mistake of upgrading to the new current Sonos app. 

I de-installed after the current Sonos app.

Re-installed the 16.1 version 'Brown app'. This time from the APKmirror  version i downloaded yesterday on my Android phone. 

All works fine again with the v16.1 Brown icon app

does anyone know where the brown S2 16.1 for IOS may be, the above has android, but not IOS

Don't shoot on me if this doesnt work, i am An Android app user but Found this:

https://www.ipa4fun.com/ipa/345019/

Thanks for that, there’s about a zillion buttons that say “download” on that page - no idea which one is genuine 

This is the potential danger Sonos are forcing some of their users to face. It doesn't take too much for a malicious actor to create  an apk and say it's Sonos 16.1 and for someone to install it and be in a world of pain.  There is a legitimate apk on apkmirror I have seen links to elsewhere on the site.

There's actually a great App on the store called apk extractor and you can use it to get an apk from a device with it installed and then use it elsewhere to get the App back.

For iOS, I'm not aware of any such similar method (sideloading etc.).

I know in the Mean time. And in the end the Point to the Apple official store. This is awfull. I read somewhere that Apple was forced to allow ipa downloads other then from the official Apple app store in the EU. I hope you find the alternative ipa file! 

I use Sonos since Dec 2005. Eventually upgraded from S1 to S2. Now this...i suspect Sonos to use it's existing customer BASE to Alpha test their new app... Disgusting

I play my music from my NAS drive and this feels like they are trying to drive me towards streaming 

Completely weird idea: buy a cheap Android phone, just use it as Sonos 'remote'.  install the 16.1 Brown app on it from APKmirror.

Actually back in 2009/2010 i did exactly that. I forgot if that was to replace my old cr100 control.

And you are right, i also use my own carefully Crafted music library on a router with SSD drive connected to it. In 2015 Spotify was launched, i naaiively  thought, great, for 12 euro  per month i get all the music, can even listen to it offline, until.   ....i stop paying for my subscription. Ok ok buying cd's is also costly.

My son is using Spotify has no NAS. He's perfectly happy him paying a Spotify, a Netflix subscription.

But that's economics...
