[Plugin: Video Thumbnails] Not working with official facebook plugin

The plugin is not working with the official facebook plugin – https://www.ads-software.com/extend/plugins/facebook/

After successfully publishing the post on my facebook page timeline with their plugin, the thumb on facebook is the default one for my blog. Then I can see that the thumb is generated successfully for my post but after trying to share the post again on facebook the default thumb is still there (I think is cashed somehow).
