Have you noticed that sometimes incorrect post thumbnails are showing up when you share articles in Facebook? Many WordPress users have been complaining about this, and sadly, this issue has not yet been fixed.
Why is Facebook not picking up the thumbnail image? There are many reasons that Facebook prevents from correctly guessing the right thumbnail image. One common issue is having multiple images set in the og:image tag where the features image is smaller than the rest of the image.
Other issues are caching plugins, CDN issue, missing open graph meta tag, etc. It is hard to guess what is causing the issue as there are no specific error messages displayed in the debugging tool.
