Did you put the correct email in? We did have an issue with someone else receiving the email ~6 hours later. If you're on discord, you can open an online support ticket and someone will help you, or you can message me here with your online account name, and I can try.
Thank you so much but I think in my case it's more than 6 hours because I never receive any email regarding rfator2 verification. I can make sure the email address used for verification is correct. outlook: lishunyu.1017@outlook.com gmail: lishunyu.1017@gmail.com
