Sepang GP tickets – has everyone received the payment link?

Hi! I booked tickets for the Sepang GP and received the reservation confirmation email, although it went straight to my spam folder.
From what I’ve seen, some people have already received the payment link, while others apparently haven’t. I’m still waiting for mine.
For those who booked tickets: have you received your payment link yet? If so, when did you get it compared with the reservation confirmation?
Just trying to figure out if they’re sending them out in batches.
Thanks!
