I had the same problems for a long time. I turned off the Yoast sitemaps and I started using the ‘standard’ sitemap from WordPress. It works smoothly and Search Console has no problems indexing.
After you switched it off just go to;
https://www.your-url.com/wp-sitemap.xml
I’ve modified some tweaks, in case you want to show more posts/pages in your feed or when you want to hide certain pages, for exampels tags of categories. Just add either of the lines below to your theme’s functions.php;
// WORDPRESS SITEMAP
// INCREASE URL COUNT FROM 1000 TO 5000 PER SITEMAP
add_filter( ‘wp_sitemaps_max_urls’, ‘filter_function_name_9755’, 10, 2 );
function filter_function_name_9755( $max_urls, $object_type ){
return 5000;
}
// REMOVE USERS FROM SITEMAP
add_filter(
‘wp_sitemaps_add_provider’,
function( $provider, $name ) {
if ( ‘users’ === $name ) {
return false;
}
return $provider;
},
10,
2);
// REMOVE CATEGORIES FROM SITEMAP
add_filter(
‘wp_sitemaps_taxonomies’,
function( $taxonomies ) {
unset( $taxonomies[‘category’] );
return $taxonomies;
}
);
// REMOVE TAGS FROM SITEMAP
add_filter(
‘wp_sitemaps_taxonomies’,
function( $taxonomies ) {
unset( $taxonomies[‘post_tag’] );
return $taxonomies;
}
);
// REMOVE PAGES FROM SITEMAP
add_filter(
‘wp_sitemaps_post_types’,
function( $post_types ) {
unset( $post_types[‘page’] );
return $post_types;
}
);
