It's not available on IPad Pro, not sure why they decided to do away with it though.
Yes, but completely missing from the iPad Pro.Just tried it out on my Air 2 with ios 9.2 and split keyboard still works.
If you put the iPad Pro in Display Zoom mode, you get back the split screen but lose the extra row of number keys that are iPP only. My guess is that the new keys on the iPP keyboard meant they had to redo the split keys for iPP, and they didn't get it done in time for release.
so, it sounds like if you take away the native resolution you can use the default air 2 setup more or less.. ugh, hopefully it'll pop back into the 9.3 release. Anyone on beta able to test it ? See if it works?
