Title: iOS Calendar Notes bug, which can lead to losing Notes for your Event
I was surprised when I found this bug, purely by chance, one day when I was editing a Calendar event and made a mistake in clearing out the Notes, which I rapidly cancelled. However, the bug is that if you Cancel a change and then press Edit, the Notes will appear to be gone. If you then save, you will have lost your Notes.
