Just updated my iPad Air 2 to iOS 9.0.2 and I've found a new bug in Aerofly 2: there's absolutely NO SHADOWS from any solid object in game except the aircraft. Also, when you fly over any building on the ground, the stencil shadow that the plane draws on the ground is switched to a translucent rectangle instead.
This bug it's not present on my wife's Mini 2 with iOS 8.x so... please IPACS, fix it asap.
