Specifically, when using an iPhone there is lots of resizing the screen and moving things around. I had become used to tapping the pull down, which would stay down, then touching another part of the screen to move the whole thing around if the link I wanted wasn't on screen.
Now, if you touch any other part of the screen, the pull down disappears. What you have to do now is open the pull down then hold it down and use IT to move the screen. I hope/think that explains the change in function.
