Just an FYI,

2FA emails still NOT showing up in email (not in the SPAM filter, not anywhere to be found, they are not arriving into my yahoo email).
I also just received a different email (marketing email) from FH into the same yahoo email address and it did not go to spam and so I know for certain that this is indeed the email I have signed up at FH and certain emails are indeed coming through but the 2fa emails are NOT coming through at all.

I tried multiple times clicking the resend 2fa email button and still nothing.
This must be a transmission issue with 'MailGun' or whatever; the 2fa email is simply not getting sent out.
Could an email with a 2fa code for validation/verification be sent out manually? Probably just need to have it validated one time as my ISP switches IP's on me only rarely. I'll try again in a few days if I don't hear anything.
Thanks
