When you select an area to type into the screen should automatically scroll up so the keyboard doesn't block the view of what you are typing. This is the only benefit of the original apple keyboard.
Unfortunately (and I’m starting to feel like I’m a broken record here), this is due to a problem in iOS’s handling of third-party keyboards. We’ve personally reported this bug to them months ago, and I assume others have as well. We hope they will fix it soon but are not holding our breaths at this point.
I apologize for the inconvenience, I know it is annoying, but hopefully not enough to put you off using PadKeys altogether.
