When logging in are you getting a "Suspicious login" showing your IP location? message or is it just asking you to PVA with option for Emails for phone number? Also do you get the reset password email?
If it gives you the suspicious login message then you should receive a message in the email about that, if not then no IG emails are going through, try this.
Request a password reset, don't actually change the pass just look for the email. Then initiate the email verification code to be sent. Wait about 2 days. Repeat process, if you login and get the suspicious login email then most likely the email verifcation code will go through this time.
Sometimes it works especially for old accounts.
