I have posted this to Quora:

• Did you have any luck to get your Page back? For those reading, this is different than losing access to your profile. Your profile, and your timeline, is for you personally, and is what you first log into. A Page is something you create for links about an interest, or a business, that you are involved in, and has its own set of followers separate from your friends list.

I just lost a Facebook Page last week (April 2020), that I created back in 2013. It had accumulated 200 followers. It was called “Three Gratitudes and The Happiness Advantage”. It was one of several pages I have created. I still have the other pages on showing on my account, but this one vanished. I have requested that the page be restored via various Facebook forms, but no one has contacted me. Nothing has gone wrong with access to my main profile, or any other page that I run. I am tracking my research on what to do about this here: web_development:social_media:facebook:dealing_with_a_vanished_facebook_page [TheGarnet Wiki] (https://www.thegarnet.net/web_development/social_media/facebook/dealing_with_a_vanished_facebook_page)
