Preview image does not show on social media (facebook)

Recently we have migrated our blog section to plasmic cms. it is up and running well. I have added social sharing links on these blogs. I have used meta override on the pages to pull the title description and preview image dynamically from the cms. But the issue is when the facebook link is clicked to share any blog it only shows a common image and link name . can someone from the team please help
