Just for the record. With iOS 9 Beta 1, SkyDemon will not even launch and crashes on first loadup screen.
I know its beta software, but some developers, like myself, run development devices as well as "stable" devices :-)
So, if you rely on SkyDemon then dont upgrade to any iOS 9 version - yet.
My (crap) GNS2000 and iOS8.4 work perfectly (as does SkyDemon on the latest stable iOS8.4)
