I'm trying to log into Null's Brawl with new Null Account but I'm not getting the pin code in my account

I just installed this app on my device and tried to log in with this account. However, I did not get the pin code for it. Is there something I’m doing wrong here?

Nvm, I found out that all of the pin codes were in my spam box. I’m good now
