Publicize is not posting to Facebook at all. It's publishing to Twitter, but not Facebook.
When we publish a blog post, we make sure all the boxes are checked for the connections we have established, yet when we go back and look after the blog post is published, the boxes are mysteriously unchecked as if it didn't even recognize that we checked the boxes.
We have 70 clients all experiencing the same issue and yes, we're are using the most recent version of Jetpack.
We also have a few clients who are experiencing malformed permalinks (going to Page not Found URL's), images not posting, etc.
However, mostly it's just not publishing at all to Facebook.
