I installed iOS 11 yesterday on my 6s Plus.  One of the features I was looking forward to was streaming music from my iPhone to multiple Airplay enabled speakers.  But this feature does not work for me on my Bowers & Wilkins speakers. I didn't think it's a hardware or firmware issue - just a software issue that iOS 11 was going to solve.
I'm not sure what Airplay 2 is? If I can stream to multiple speakers from my Macbook Pro (through iTunes and Airfoil) why can't I from my iPhone?
