Glad to hear you're making progress. For the App ID in Autotune, simply hit the "Refresh" button in the top menu bar and that will re-fetch your Facebook settings based on your App ID and Secret Key configured.
For the SSL certificate, I hope you figure out the issue. It's always possible that the checker I mentioned is incorrect, but best to check with your host. Most all browsers have the intermediate certificate already installed (I think), but you can never be too cautious since, if incorrect, some users won't be able to browse your site.
Anyways, should you need anything else from us or have any questions in general, 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,
