I've done each of those steps repeatedly. My email address hasn't changed, and it is filled in on every single entry it can be. What's more, as I said, I've tried changing it on this form to something fake and it never gets updated on my account. So this form comes up and forces me to fill it in, then does nothing with that information.
My problem still exists, your suggestion did not help.
