I did add our own FB app just now.(btw...he documentation is outdated) a novice might get lost....however I was able to get it to work.
I still have the same issue on the Facebook posts.
It's not showing the url and I have it set to show the url on Twitter.
but on the facebook post its still showing the "message"
right now it's set to article title.
but it looks strange as the post on facebook, since shows the article title..or the article text or both (whatever we have it set to) and then repeats the article image and small text excerpt from the site..no matter what we select the data is repeated.
