iOS7 had the issue and then an update allowed us to turn stuff off and it was gone. Even with animations I could tap / close / tap and the taps registered. With 9 the taps no longer register.
That's the problem. iOS 9.x devices are the only devices where I have this issue. I don't plan on adjusting my "global" habits just because iOS has an issue. I am just using those devices far less (iOS) than I was. Hope Apple fixes it soon.
in the world of software development THAT is one of the "set in stone" commandments.
