This a bug report (I think):
In order to have a proper description on Facebook of my blog, I entered in Menu/SEO/Social and under the field "Frontpage settings" I inserted a short description + one image.
But surprise, when I post something about my site (homepage) on Facebook, the image is ok but the description is wrong, not the words from the "Description" field of Social module.
Checking my site on Object Debugger of Facebook, I discovered that the image is the same (so the modification was recognized by FCB), but the words from "Description" field are not anywhere. The row "og:description" contain a decription from my last post. So is a communication problem between Yoast and Facebook.
I think is very simple to repair this bug! I wait the update! Is very important for all the users!
