The help menu has a “PDF Nomad Help” menu item. Clicking that should bring up the user guide, but a quick test just now shows that in the App Store version the help file doesn’t appear. Am I correct then to assume you are using the App Store version?
If so, I,m sorry to say that the App Store flavour of version 2.0 is missing the scanner import menu item. We’ve already submitted to Apple version 2.0.1, which adds in the missing menu item (and corrects a few other bugs). We are expecting the update to become available before the end of the week, depending on Apple’s review process. If you need access to scanning a.s.a.p contacts us by email, so that we can provide an interim solution for you.
