I love using this app, but I put auto capitalization, auto correction, editing & it doesn't do ANY OF IT?!?! When I'm typing I have to go back & forth to correct things!! It doesn't even let me see where I'm at when I'm typing so I have to delete letters to see where I'm at. VERY FRUSTRATING!! When I want to copy & paste, so I can save to documents, it won't do that either? Am I doing something wrong or is this something (bugs needing to be fixed?) on your end? HELP PLEASE?!
