Hello,
Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.
If you don’t have any other page with the same content, the URL should match the current URL so Google would know that this content doesn’t have duplicate content. More info about it here: https://techcrawlr.com/what-is-google-user-declared-canonical/#What_is_Google_user-declared_canonical
We would like to further check the GSC link you shared but it is an invalid link.
Can you please share a screenshot of the GSC issue instead, showing the affected URL so we can take a closer look at it? You may use this tool https://imgbb.com/ to upload your screenshot and share the URL here.
Looking forward to helping you with this one.
i have uploaded this is link https://ibb.co/3STp4Pf but brother there is no problem in indexing after showing this my post got indexed in 4 hours.but always shows user declared canonical after publishing post
Hello,
We can confirm that Google is referencing the same URL you declared as canonical so you can safely ignore the message from GSC as Google is already indexing the page.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
