It does put Open Graph meta tags in, but the url is not correct. The url for the link used by Facebook will go to the correct article.
Ease of use
Easy to install and setup. Passes wrong canonical link to Facebook and thus you get the wrong image displayed in your posts.
Paid support for a free extension is a trap when the extension does not work as advertised.
Does not contain a manual for use. Documentation link goes to download page.
