Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
Since most users expect to see the sitemap on the sitemap.xml, Rank Math redirects sitemap.xml to sitemap_index.xml just to prevent any kind of issues. You shouldn’t be worried because it is harmless and completely normal.
Hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
Thank you.
