ML accepts are not happening currently, I believe since November 27, but ML rejects started back up again as early as December 4. You can check for the “Wayfarer criteria” rejection reason if you can’t check the email.
I get very confused around email issues so will let someone else try to answer that. It is usually something around being logged in to your game in a way that has a different email. Or something about Apple logins. I am an Android user.
