I'm using Evernote on iPhone and Windows laptop. The problem is that I lost 3 notes during last few days. When I open some random note either on phone or laptop, I see the content of another note, so the previous information fully disappeared. I don't have function of history of notes and I checked web-version of Evernote. What can I do to prevent such a problem in future and can I restore my notes if I didn't make export of notes before?
