It could be so handy but it's so annoying that I HAVE to sign into the HP account to do anything else than print. Additionally, when I do attempt to sign in, it tells me that my credentials are invalid— even when I change the password, and even when it signs in just fine through the webpage. It also keeps logging me out whenever it decides to work, so I have to do the entire fiasco over and over again until I get lucky! Please fix that! This app is unusable on my phone otherwise.
