Problems logging in on desktop

I'm having trouble logging in on desktop.
It says something about my account not being activated and it sent me an email. But when I check, there's no email.

Check your spam folder?

Maybe you're somehow in Incognito mode?

I think you have the same problem I had. How do you log in, with your username or email address?

Checked spam folder. Not in there.

I never use incognito mode.

I've deleted my cookies and everything too.

I've tried logging in using both

I had this same exact problem.
After trying multiple times and failing, I just came back and tried it again, and there it was in my Email.
I have no idea what caused it or why it only sent that Email the last time I tried.
