Continuation of Exclude Custom Post Type with specific status from Sitemap #4093

Hi,

Some time passed until I heard from our theme developer. He sent me a code snippet which doesn’t work, so I went ahead and wanted to test whether having a double robots tag which basically both says noindex would be a temporary fix. I went ahead and tested it on one specific job which Google is giving me an error for: https://fiks.nl/vacature/skillz-talent-workforce-communicatie-marketing-stage-sittard-12290/

#-----------------------------------------------------------------#
# Rank Math: filter the robots meta data.
# @param array $robots The meta robots directives.
# Remove action in wp_head
#-----------------------------------------------------------------#

add_filter( 'rank_math/frontend/robots', function( $robots ) {
	if(get_post_type() == 'job_listing' && get_post_meta( get_the_ID(), '_filled', true )  && get_the_ID() == '12852') {
		$robots["index"] = 'noindex';
		$robots["follow"] = 'follow';
	}
	return $robots;
});

As you can see in the html it says ‘noindex’ twice now, so that works. The odd thing, it stays in my sitemap. I flushed the sitemap, cleared my website cache and made sure my sitemap isn’t cached as explained by Reinelle.

My sitemap can be found here: https://fiks.nl/job_listing-sitemap.xml

What else can I do? Looking forward to your answers. Thanks so much!
