I have an iPad 4 and I've accumulated quite a few notes over time but yesterday I opened notes and in a split second I saw them disappear. I did the latest IOS update a couple of days ago so don't know if these things are related or not. Anyway it's probably been 2 or 3 months since I backed up my iPad by hooking it up to iTunes so I haven't tried that. Does the iTunes backup usually backup contents in the Notes app? Is this what I should do or are there other options to recover my notes?
