Hello @TomF137 ,
When you select that option in the Resend... pop-up menu, you should see one of the following screens (depending on how old the email is):
If neither window is appearing, then it's definitely some kind of connectivity issue when trying to work in the site, since I was able to get both of those little windows to appear properly in your account. I'd suggest starting with some basic connectivity troubleshooting. Please keep in mind that when I say connectivity issues, I'm not necessarily referring to just your internet speed. There are a number of elements that can affect website connectivity and accessibility on an individual basis - particularly network settings, VPN restrictions, and addon/plugin/extension interference.
If none of those alleviate the issues, please call our general support number so they can continue troubleshooting with you live. If possible, please have a screenshot of your speed test, including the More Info section, ready for the phone agent.
