Glad to hear we could help. The little button doesn't really stand out.. it's something we're hoping to make more obvious in the future since it can help with a lot of different issues and configuration settings.
Either way, happy to hear you got it going. As always, should you need anything else, just let me know!
Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:

Thanks,
