I am not sure how / if I am seeing all notifications on my iPad 2, running 4.3.3. I'll get notified of a bunch of notifications, from email, calendar, apps, etc. When I click through each one, sometimes I'll click on "View". As soon as I view one, it seems there should be more notifications but no more notifications show up. How can I make sure I have viewed all notifications? Is there a way to view prior notifications that I closed?
