Thank You for your help, I have used the shortcode of checkout inside the builder, which was not supported by this plugin, now I have placed the shortcode of checkout in the WP editor, and it works fine.

Thank You

I assign both, parent and child.

Hi @hcabrera,
Here is the code which gets the top-level category.

function smart_category_top_parent_id ($catid) {
	while ($catid) {
		$cat = get_category($catid);
		$catid = $cat->category_parent; 
		$catParent = $cat->cat_ID;
	}
	return $catParent;
}

$postID =  get_queried_object_id();

$category = get_the_category( $postID );
$catid = $category[0]->cat_ID;

$top_level_cat = smart_category_top_parent_id ($catid);

I’m impressed with this fast response. Thank You very much.
This solution solved the problem. I have tweaked it a bit to work as per my requirement for more than 1 custom field.

/**

function wpp_thumbnail_fallback( $img_url, $post_id ) {

    // Post  doesn't have a thumbnail so let's fallback 
    // to the custom field one
    if ( ! has_post_thumbnail( $post_id ) ) {
        // Get the image URL from your custom field here
        // and then assign it to $img_url or return your URL
		if( get_field('graphic_910x512', $post_id) ){
          		$image_url_linkedin = get_field('graphic_910x512', $post_id);
				$img_url =  $image_url_linkedin['url'];
		}
		else if( get_field('graphic_683x512', $post_id) ){
          		$image_url_linkedin = get_field('graphic_683x512', $post_id);
				$img_url =  $image_url_linkedin['url'];
		}
		else if( get_field('xxl_graphic', $post_id) ){
          		$image_url_linkedin = get_field('xxl_graphic', $post_id);
				$img_url =  $image_url_linkedin['url'];
		}
		
    }

    return $img_url;
