This app is laid out quite well but the ability of staying logged into it or getting logged into it is severely lacking. I can't scan without it (although thankfully I can print without it) and I have had to change my password multiple times because it either won't retain the password I put in or it scrambles something. In my opinion there should only be a need to log in with a password if I'm going to purchase something otherwise this is an absolutely superfluous action that prevents full use.
