Hi, the same thing happened to me just now. I was making a really long note on the Mac Evernote app, and I decided to check if it's been synced to my Iphone as I was planning to work from the phone instead, then the note showed up for a second and it suddenly ended up as a blank note. I was not on Premium, and when I read that I can check history once I activate Premium, I did. When I checked history as a Premium account user, there is no history saved. Can someone help me in this please? This is very frustrating as I trusted Evernote to sync my important note. :(
