Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Could you please head over to Rank Math > Titles & Meta > Posts and check whether the Post Robots Meta has been set to noindex? If so, please disable this option and set this option to Default
This should then fix the issue.
Looking forward to helping you. Thank you.
