I have logged in before, but today I was asked to log in again, but I have not received a confirmation email until now
Confirmation mail? By right, there's no need to confirm any email because the page would request for your email, address and 2FA (assuming you have it activated).
The site says I'll receive a confirmation e-mail even with 2FA activated. And I'm still waiting for it, I asked for a withdraw a couple minutes ago.
