Cannot get Comments on both WP site or FB page

Hello! Love this plugin and its simplicity! However, I can’t get it to fully work.

If I post a comment on my WP site I can get the comments to show only on the WP site. They will not cross over to my FB page. And vice versa: comments posted on FB will not come over to WP. The sites are: https://www.facebook.com/absolutenews and https://www.absolute-news.com.

A page with a FB comment is: https://wp.me/p4q7aw-2ni but the comment is not coming over from FB. (Someone posted a comment on FB but it is not showing on the WP post.)

A WP page I posted a test comment to is: https://wp.me/p4q7aw-2ni but the comment is not being carried over to FB.

Feel free to make some test comments on FB and a WP post.

Appreciate your help! I’ve spent hours trying to debug and research but no luck. Thanks!
