At around 12:20pm, after hours of trying anything I could, the Desktop version of Facebook Web's Meta AI Support asked me to upload a video selfie. Then it asked me when the issue began, and as soon as I said around 7am this morning, their AI was like "Ah ha!" -- It asked me for my alternate email address, which I provided, and as soon as I clicked a link in that email, I started getting email about Pages being republished, access to Marketplace being restored, etc.
Now: Can I even prevent this from happening in future? How can I make sure everyone has my blog url (or phone number) so they can contact me even if I lose contact with them?
Thank you for your support and concern, despite however dumb my comments in 2009 were. LOL.
