I switched phones without first transferring Google Authenticator and this year have been locked out of my Facebook account on everything except Meta's iOS apps.

This twitter user essentially documented the exact flow of my issue:

Ben Ratner on Twitter: "I believe that Facebook has an issue with their 2FA/Code Generator/Text Message system for logging in to their platform - as well as support for it. I've seen this issue a few times on other devices - and I'm experiencing it now as I prepare to upgrade to a new iPhone." / Twitter

I have tried all of the solutions on Facebook's 'help' pages to no avail and am now having to think outside the box. I have been unable to interact with any human support from Facebook other than their VR team.

I will award bounties in estimated proportion to how much they played a part in me getting access back.

If you think your tip will help, you can bet on whether or not it will work out at all here:

Big update! I was able to pay for Meta verification and it appears there is a live support option. 

Update: For the first time ever, I was able to talk to a real human from Meta without having to pretend I wanted to buy one of their vitual reality devices. They collected my info and told me they would pass it on to a dedicated team, but I have not gotten an email

8/28/23: There seem to be two tiers of support. Inbound frontline support and then technical support to whom they escalate. I have been allegedly escalated to that second level of support, but have not heard from them at all and the front line support keeps trying to get me to close the ticket with assurances that I'll hear from the tech folks soon...
