问题
I try unlinking apple porvider as sign In for my firebase auth.
The unlink is successful but the email still presist, so when the user sign in with apple again it allows them to read their data because of the email persistence.
The problem is not local or cache problem, its firebase not erasing email record since I can see the Apple email as an identitifer while the Apple logo for provider goes away when I unlink.
I am using Phone Auth, and option to link Apple. How do I remove email from Apple when unlinking?
