Divi - Sitemap shows only one language if you use Divi, Yoast SEO and domain per language as your URL format setting

Overview of the issue

When using Divi and Yoast SEO with WPML, sitemaps won’t appear as expected if you set the language URL format as A different domain per language.

Instead, it will only show the sitemap for the last language you used before turning on the Yoast XML sitemap option.

For example, if you select a secondary language and turn that option off and then on again, the sitemap will show up in that specific language only. It will show the same links in the sitemap for all domains while it should show a different/correct links for each domain.

Workaround

Add the following code to your functions.php file:

add_filter( 'wpseo_enable_xml_sitemap_transient_caching' , '__return_false' ,11);
