Vanishing Calendar Entries
During June and July 2013 I kept a log of all my activities in my iPad calendar. Tonight I wanted to view the records I had made in the calendar, but the log entries have all vanished. I updated my calendar several times each week between June 1 and July 19, and each time I made a new entry my prior entries were still viewable on the calendar, so I am mystified as to how they all could have completely disappeared.
Is there any way I could go about to recover or restore the entries I made? Does anyone have any idea where I might look, or how I might go about finding the notes I made in the calendar during those weeks?
Thanks for any tips!
