Facebook archived notes years ago and truth be told I forgot about mine until recently. Some of what I am posting now is thanks to the following PC tip I randomly bumped into through Facebook groups.
Copy your Facebook URL, e.g.: https://www.facebook.com/YungJayWonder
Add archive string command. i.e.: /allactivity/?category_key=notecluster
Combine and hit the enter key, and you’ll be taken to all of your published notes.
It seems they were set to live with stories but since they were so old they got set to a bin, this trick didn’t work on Chrome’s android mobile app but might be worth trying on other mobile browsers.
