In one of my frequently used Notes, a few lines of text "disappeared" earlier this week ....... I definitely did NOT delete that text myself. I found a link called "Note History", but when I clicked on it, it asked me to UPGRADE (from Evernote Free) to one of the premium plans. a. If I upgrade to Evernote Personal, will I be able to access Note History (and be able to access the Note text that existed last week)? b. There is a "40% off" promotion (expiring in 2 days). Is this "40% off" the monthly rate permanently, or does it expire after the initial year, or after a few months?
