Trick to get it to work proper on iPad Air 2/iOS 8.4, is dont allow Full Access in System keyboard settings. (Had to delete app and reinstall to reset but working okay now.)
Some great features in this app.
Would like ability to adjust/set cursor scroll speed when slide space bar to move cursor.
Also keyboard covers bottom lines of text in landscape mode (like while trying to write this review) so have to use portrait mode.
