sitemap not updating new urls in gsc sitemaps

Hello, I’m facing issues with sitemap_index.xml. sitemap is not updating in google search console. i am using lite speed cache plugin and sitemap url is excluded from cache by .xml. and also there is no server side caching enabled. The problem is that only manually submitting sitemap_index.xml in search console not updating new urls in gsc & then shows indexed not submitted in sitemap in url inspection. (These cause late indexing of new post. I checked many times) To avoid this I have submitted post-sitemap.xml child sitemap in gsc with sitemap_index.xml. when i resubmit manually post-sitemap.xml in gsc new posts update in both sitemaps instantly. But it also adding two referring sitemap urls in gsc url inspection referring sitemap. i.e post-sitemap.xml and sitemap_index.xml. is it ok to add child sitemap url in gsc with main? Because resubmitting child sitemap is instantly updating new urls in both sitemaps.

Hello @mayur095

Thanks for reaching out regarding your sitemap. First, we recommend only submitting the /sitemap_index.xml/. If you have the child sitemaps, too, please remove them.

Do you mean that there are URLs on your website that aren’t in the sitemap?

indexed not submitted in sitemap in url inspection

It means Google found this particular URL through other means, not the submitted sitemap. It’s a valid URL and is indeed indexed and appearing in the search results. You can learn more about the different statuses in the index coverage report documentation –?https://support.google.com/webmasters/answer/7440203/
