I frequently use the built-in Notes app on my iPad (1st Generation); however, the notes I create randomly delete themselves. For example, I took notes during a meeting last night and when I opened the app this morning to review my notes they were gone. Other times, I have opened the App and watched them delete one by one. No other apps are running at the time so I have been very confused why this happens. Has anyone else experienced this or know what I can do about it?
