[Infra] 2 issues about QuickIssue

Hi Infra team, Firstly, many thanks to you for offering QuickIssue on the web. I would like to report 2 issues. 1. gmail doesn't receive the verification code every time. I tried twice but the first one failed. The second one was received after around 2 minutes before I abandoned it. 2. I filled in email address 1, and clicked the verification button. As the verification code was not received, I changed to the other email address, but the verification button was not valid as the time counting had not expired. I am wondering since the email address was changed, the verification button should be valid immediately. Best regards -- Regards Fred Li (李永乐)
