It seems that the plugin grabs the 1’st image in the post which is not necessarily the featured image.
nickelaos92, Lethalmiko, omriamos and everybody else with the same issue. PLEASE, PLEASE, PLEASE UNDERSTAND.
I would love to solve your issue. I would really, really, really would love to do that.
BUT FACEBOOK TOOK OFF THAT POSSIBILITY FROM US
You are saying “plugin grabs”. It’s not the way is works anymore. Facebook removed the ability for plugin to grab anything on July 18th.
Plugin can’t control image, title and description of the shared links anymore.
Please set your OG tags correctly. Nothing else can be done.
Please see the explanation of how it changed again:
How SNAP worked before the July 18, 2017.
1. You hit “Publish” button.
2. WordPress changes the status of the post to “published” and calls the special hook from SNAP attached to that event.
2. SNAP collects the post info, then calls Facebook and says “Hi Facebook. Here the URL of the link I want to publish on my Facebook page, this is the title for that link, this is the description, this is the image”.
3. Facebook publishes the link with provided title, description and image

3. Facebook visits the provided URL, collects title, description and image from OG metatags and than publishes the link with collected from OG tags title, description and image.
