When selecting a passage, as per the screenshot below, I am able to share to various social networking sites (including Faithlife).

When sharing to Faithlife, the highlighted section of the book is quoted and a link to the resources (via Biblia) is provided as per below. This is really impressive.

When sharing to Facebook, however, only the link to Biblia is provided (i.e. no text),

I was wondering if this was a bug, by design or a limitation with Facebook? I note that when I share articles/blogs from other websites a truncated extract of said article is typically reproduced in Facebook with a link to the source website.
It would be good to have full parity when sharing to FB.
