Note on notes app completely vanished:
I recently pushed 'select all' on a note on a My iPhone folder and then pushed the back button to the folder, after which, the whole note was gone. It isn't in the recently deleted folder for either iCloud of My iPhone, and the shake or 3 finger method to recover recently deleted content didn't work. Going through the notes app via iCloud and turning it on and off didn't yield any results either. It's as if all data concerning the specific note had completely vanished after a small error.
This was a very important note I'd very much like to recover and I see that many others have experienced the same issue but none of the posts have any helpful advice. Most of the posts are now years old so I'm hoping this problem has been remedied.
