Not what you're looking for, but as one data point I have the MS Universal Foldable Keyboard and shortcuts work on my Air 2 with iOS9.
Well it's good to hear that it does work. Did you do anything outside of just pairing it up via bluetooth?
Nothing, just paired it. Did you doublecheck the setting of the operating system switch to make sure it's set to iOS?
Oh, I didn't think that mattered. I have my iPhone on the iPhone/iPad switch, and my iPad on the Android switch. I just assumed they were just handy labels for you to switch between 3 generic devices. Thanks! I will try it out when I get home.
That should do it. I tried it out - I set my keyboard switch to Android and the shortcuts didn't work; I set it back to iOS and they did.
