Hey, everyone: After upgrading my wife's iPad Air 2, she is upset that the key order in the virtual keyboard has changed--the "@" and hyphen have apparently switched rows (?). And she also hates the large "Undo" button, which she accidentally taps instead of the space bar, and then unintentionally deletes text. Frustrating, for sure. Is she losing her mind, or is the layout definitely different vs iOS 10? Any way to fix/revert? Thanks!
