How do I determine which of my Sonos products are not compatible with S2?

I am trying to figure out which of my Sonos products are not compatible with S2.  I downloaded the S2 app, but it tells me it found products on my network that are not compatible with S2.  I’ve looked at the compatibility page, and it appears all my products should be compatible with S2 - I have a number of Play1’s, Play5’s (2nd gen), playbars and subs.  My full product list is below.  Which one(s) is not compatible?
