Troubleshooting Relume Site Builder Import Issues in Webflow

Hello! I am new to Relume and Webflow. I've tried the Relume Site Builder Import several times this evening and it hangs every time displaying "Importing This may take a few minutes". It seems to start importing the home page (blank) and then just hangs. I tried via an incognito window as well with the same failure. How can I make it work? Thanks!
