Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
You should only add to the Google Search console the https://yourwesbite.com/sitemap_index.xml URL so you should remove the sitemaps you have added in the Search Console and add that one.
Let us know if that fixes your issue.
Looking forward to helping you. Thank you.
Yup! I’ve added the one that you’ve said.
The problem solved automatically after the coverage issue was fixed in GSC.
Thanks.
