Missing Link in Facebook Mobile

This Plugin works so far for Twitter and on Facebook at my Desktop.

But in the mobile Facebook App, there ist no link to click. I set “Include Link” to “Yes” of course.

I tried with and without URL Shortener and with and without Google Analytics Tracking.

I also tried to “Fetch URL From Custom Field”. Same Result.

Somethimes there is a small Image at the Facebook posts and then there is a clickable link right beside the image.

But most of the time there is a big Image an nothing zu click.
