Missing ThumbnailURL

Hello,

Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.

Please ensure you are using the latest version of Rank math.

You can also head over to your theme editor and add the following to the functions.php file

add_filter( "rank_math/snippet/rich_snippet_videoobject_entity", function( $entity ) {
	global $post;
 $featured_img_url = get_the_post_thumbnail_url($post->ID,'full'); 
    $entity['thumbnailUrl'] = $featured_img_url;
    return $entity;
});

Looking forward to helping you. Thank you.
