Deleted my Aunt's important notes and I can't find it.

Hello!

My senior Aunt lives in Florida and I tried to help her with some tech support from Illinois. We've mastered FaceTiming and allowing me to take control of her phone and computer to help her.

Her AOL account in her native mail app wasn't connected and it said she had the wrong password. It wouldn't accept any password she put in, so we went to the AOL site and updated her password. To make things easier, I deleted the Mail account entirely from her phone, and re-signed back in. Fixed that problem and all was good.

This morning she called me frantic that a very important Note was missing. First, I confirmed that the Notes toggle was turned on in the AOL Account, it originally wasn't, but we turned it on. Important note not there. Then I checked her Notes app and she has Notes that are saved locally "On This iPhone", on iCloud, and on AOL. I searched a keyword in one of the missing notes and got nothing. Thinking AOL might only show a certain time period, I went to AOL's site and looked at her notes. There are notes there, but not the one she's missing. I looked in her deleted mail folder on AOL and they weren't there. I went to iCloud's site and searched the same thing, and it's not there. I looked in her deleted notes on her iPhone and it wasn't there.

I've tried everything I can think of except restoring her phone from a backup, but even that, I'm not positive would bring the note back depending on where it was stored originally.

She's devastated, and even though she is handling it well, I feel terrible about it.

Is there anything else I'm not thinking of? TIA
