Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Your sitemap is working as expected, I’ve also validated it on the following page just to be sure: https://www.xml-sitemaps.com/validate-xml-sitemap.html
I can suggest that you clear your cache and then resubmit your sitemap and then give this a few days.
There does not seem to be any robots.txt related issues as well. Please let us know the URLs that are reporting this error so that we can investigate further.
Looking forward to helping you. Thank you.
Thank you so much! I will clear my cache again and resubmit. Glad to hear the robots.txt stopped coming up as well. Have a nice day.
