Hello,
Thanks for contacting us and sorry for any inconvenience that might have been caused due to that.
Please make sure that you have enabled the AMP module of Rank Math from WP Dashboard > Rank Math > Dashboard.
If the issue persists even after that then please share some screenshots of the issue so we can check and assist you further. You can use a tool like https://imgbb.com to share the screenshots.
We really look forward to helping you.
