Missing all but 2 of my local Notes after iOS 10.0.2 update
I backed up my iPhone 6s with iTunes 12.5.1.21 and then installed iOS 10.0.2. Now my extensive list of local notes has dwindled to only 2. I had the Notes app set to store them "On My iPhone" because I have had trouble with notes disappearing when the app would sync with iCloud in the past.
It seems there's no way to prevent losing data with this app.
I don't see any Notes listed in iTunes for my device either and the Notes app on my Mac has no saved notes, since I have never used it.
Any help would be appreciated regarding recovery and future prevention.
These are important notes that I can't simply rewrite from my personal memory.
iPhone 6s, iOS 10.0.2
