Hello,
Thank you for contacting Rank Math.
If you want Google to not index your website when it is under construction, please head over to WordPress settings > Reading > Check the discourage checkbox
Rank Math creates a dynamic sitemap and updates it whenever you publish new post/page.
Make sure you have excluded the Sitemap files of the Rank Math plugin in your caching plugin. The cache could be via a plugin or from the server. For plugins or Cloudflare, please follow this article:
https://rankmath.com/kb/exclude-sitemaps-from-caching/
Also, you only have to submit the sitemap_index.xml
in the search console.
I hope this helps. Looking forward to helping you.
