Bug when embedding videos

Found an issue when embedding videos into posts (attach featured video function)

If I use a Youtube video URL, it works fine. The video shows and plays as expected within the post.

However, using a Facebook video URL, it shows the video when creating the post, but when I post it the video dissapears and only the posts title and text show.

In regular WP blog posts, both display as expected and within regular WP pages.

The issue only happens within Fluent Community posts.

Please can this be looked at as Im looking at using Fluent for importing some FB groups I have which are very video based so would really need this feature to work!

Thanks

ps - as a test I added a FB video to this post as featured video but it doesnt show!
