I noticed this recently when using the most updated version of the plugin (2.5.3)
Generally, if a Video Thumbnail is edited on Vimeo / Youtube, we can go inside the content item in WordPress, click "Reset Video Thumbnail", click update, and we're all good to go.
Now, it seems that, while it's updating the "_video_thumbnail" parameter in the database, it is not updating the "_thumbnail_id" for the post, which many plugins and themes use to decide the Featured Image.
The initial creation of the post writes the "_thumbnail_id" and file to the Media Library without issue, we're just not seeing the ID update on Reset.
Is there a quick fix to this? Does this perhaps happen differently in the Pro version?
Let me know if you could as we're looking to use this plugin for a number of sites. Thanks!
