I'm having two big problems. First, when I leave Evernote open on my iPad, close the iPad, and then reopen it, the note I am working on either disappears, or for some reason creates a new note from a template, overwriting my work. This can happen even when I'm sure to sync before closing the iPad. "Undo" will not recover previous work. Also, if I am working in a shared notebook, it doesn't even save the note history! This caused me to lose all my notes from hours of a session with a highly paid consultant.
