I had to factory reset my phone, which logged me out of and deleted all apps. When I downloaded Facebook again, it will not let me log in without a code that gets texted to my phone. Facebook has an old phone number of mine- (***-***-****). I have a new number, but when I try to use it, it logs me into a stranger's Facebook account. I assume we have the same phone number. Anyways, to add, my Facebook username is an email I can no longer access. (*****@***.com) so I literally have no way of getting into my account. Also, I've waited over ** hours to retry sending a code my number so I can try logging in again, but even after ** hours it still tells me to keep waiting and doesn't specify how long.
