One of the main purposes of an app like this is to facilitate quick print jobs. In that, it fails. It took me 25 mins of fiddling to determine that it wasn't going to be practical to use FedExOffice . And I am a quick study with this stuff...
I downloaded FedExOffice , created an account, linked my account with Google Drive, added a file from Google Drive, initiated the print job, searched for and selected a store for pickup, added credit card information (why am I asked to type my name twice?), then was told the minimum order is $1.00 (why not notify users earlier?), so I went back and ordered more printouts, had to search for and select the store(why not save this from the previous session?), added credit card info (again typing my name twice), got through checkout, and was informed my printout would be ready to pick up in two hours(why not warn consumers at beginning of this process?).
I was standing in the store when I got this unwelcome news. So I asked the store associate for help and, though friendly, he was unable to move the print job up for me. I ended up abandoning that job and using the email to Fedex option which was very fast.
Fedex, I feel like the user interface stuff you missed is really basic, like 101 stuff. Get it right before you launch it. Deleted.
