I had a poor connection and then all of a sudden none of the saving or sharing buttons would do anything. Every time I open the app it says it failed to save a file, um why not save it locally in my own Evernote app? Also switching to network and off wifi I had a decent connection but the app was still unresponsive in this state. Cannot even submit feedback because of the connection (why cant I go through email?). Also has bugs where they tried to print a integer but shows an optional integer on the recents page for how long until the scans are deleted.
