I guess there is a delay which should be fixed soon since it's not possible to sign in with a code that is valid for 10 minutes but receive it 1 hour later.
I believe moonton is already working on a fix.
I'm also experiencing this issue. Yesterday, I was receiving the confirmation email a few hours after. I've just receive bulk of emails today which I believe came from the times I tried to login last night.
I got to switch my acc now. Apparenty, receiving the code for yesterday's code seems to work as long as it is within 10 mins of receiving the email or idk i'm not sure but it worked!!
Hey guys..
we apologize for the inconvenience, especially the issue of email verification code during the 515 eparty event which makes you guys probably missed lots of event
but now the issue has been solved
