Hello,
Thank you for contacting Rank Math, and sorry for the inconvenience caused.
The reason why sitemap.xml is not working is that Rank Math creates the virtual sitemap as sitemap_index.xml.
Your Post/Pages should appear in the sitemap_index.xml file.
I hope this helps. Looking forward to helping you.
