For a few weeks now whenever I attempt to login to my speedrun.com account "Bernie" the 2-factor email simply does not send. I am certain that I am using the correct email since I can see the previous verification emails. I have also checked my spam folder and still nothing. Just wondering if this is a common issue or if there is a fix that I am not thinking about.

I dunno if it was coincidence, but when I had that issue, it resolved when I disabled my ad blocker extension. Give that a try maybe. If not, try a different browser to try to narrow down the potential causes.

I've had regular issues with it arriving late by up to several hours, but never simply not arriving altogether. Have you tried adding the "no-reply" speedrun address to your contacts list?
