Hello,
We apologize for the inconvenience you’re experiencing with listing your plugin’s sitemap in our sitemap_index.xml. Based on the code snippet you’ve provided, it seems that the filter hook you’re using is incorrect. The correct filter hook to add links in the new sitemap is ‘rank_math/sitemap/{$type}/content’, not ‘rank_math/sitemap/index’.
You can use the following code to add your custom sitemap link:
add_filter( 'rank_math/sitemap/custom/content', function() {
return '

2020-09-14T20:34:15+00:00
';
} );
Please replace the ‘custom’ in the filter hook with the type of sitemap you are adding. After adding this code to your theme’s functions.php file, your custom sitemap link should be included in the sitemap_index.xml.
If you prefer a UI-based method, unfortunately, at the moment, adding custom sitemaps can only be done through filters. However, we are continuously working on improving our user interface, and your feedback is valuable to us.
If you have any further questions or need additional assistance, please feel free to reach out. We’re here to help!
