Awesome! We're glad to hear that got things going for you. I'm assuming in their next release they'll update the Open Graph tags with the fix you posted above.
If you run into anything else, or have any other questions, 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,
