Hello,

Thank you for contacting Rank Math today.

I checked your URL with Google AMP Test tool and it seems valid from my end without any issues, here is the result URL: https://search.google.com/test/amp?id=vmTjqZJmgicUItRzHPGm_g

Please try validating the URL again on your GSC.

Looking forward to helping you. Thank you.
