Referenced AMP URL is self-canonical AMP ERROR

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.

Could you please confirm if this is the AMP plugin that you’re using?
https://wordpress.org/plugins/better-amp/

If so, you can follow the filter mentioned in this ticket:
https://support.rankmath.com/ticket/referenced-amp-url-is-self-canonical-amp-11/?view=all

The filter should be added to your active theme’s functions.php file. Here’s another way to apply the filter using the rankmath.php file:

I hope that helps.

Thank you.
