Youtube thumbnail

Hi. I am managing a site with Sydney Pro. When I try to share a post with a video from you tube, the thumbnail is the same image as the logo image. I need to watch a miniature YouTube video. Would you know what the problem might be?
I have this problem with Facebook and whatsap for the moment.

Hello there,

Facebook will look for the image attached to the page you share instead of the embedded video’s image thumbnail.

You could use the Yoast SEO plugin to select an image of your choice. Read this post for complete guide (go to “Explicitly Tell Facebook To Use Thumbnail of Your Choice” section).
