We are experiencing the same results, but it only happens when you share a link that's "never" been shared on Facebook. If you either share the link to Facebook on web first or run it through the Sharing Debugger tool before opening the share sheet the preview shows fine.

This makes it sound like the issue is not in the SDK but in the Facebook app (or more specifically the ios sharing extension) itself.
