I've the same problem numerous users seem to have and there does not appear to be a solution. I have followed all of the threads which would seem to indicate there is a resolution, however none of them appear to solve the actual problem.
I am not receiving password recovery emails/links from Facebook. I had forgotten my password and from changing employment no longer have access to my account. This problem is because I have just upgraded my phone.
I have even had my acccount blocked for trying to many times to get a password (forgot password link) and I have had to engage my 3 trusted contacts to provide me with a code multiple times; which they did. After you do this it say's it is sending you an email.
