snapshot view key button not working in The Hub

Hi, I have installed the new snapshot update that allows full integration with The Hub & performs backups to the cloud. In the site admin, I click on the link to get my secret code to set the backup going. This takes me to My Websites under The Hub but the button 'View Key' doesn't seem to do anything, it won't show me a code or anything at all in fact.
I'm using Safari to browse, running an a MacBook Air. Is this a browser issue or is this feature not meant to be running yet?
