The S2 upgrading and dumping S1 devices has been a disaster.
I realised before upgrading that my play 5 would have to remain on separate S1 system. That's seemed annoying and odd but OK as is separate from rest of house so have both apps for just there. Odd the upgrade wouldn’t just make the old device ungroupable with newer ones...that would have been sensible thing to do and least impact to customers….but money racket meant that didn’t happen.
However the kids have old iphone 5 that does not install S2. Had not spotted thatn. That means some sonos in house needs to be S1 too to use sonos in their rooms on their old iphone as they were. Swapped around phones to upgrade one phone and now S1 will no longer install on anything less the ios 11 despite working before swapping around. So all expect the new phone are useless.
Total disaster, how are the kids able to control their sonos now as can't install S1 on iphone 5 anymore either.

You may want to look at SonoPhone, which works with iOS 8 or above. For $2.99 you may be able to avert ‘total disaster’.
