One of the mains reasons why the popular social media platform is not selecting the right thumbnail image of your post is because there are many images lined up for the same.

Once it comes with the result, click Scrape Again button (sometime twice or thrice) until it shows you the right thumbnail on your WP post.

Here, open the social tab and give a title and description to the post for its Facebook sharing.
