EDIT:
POINT 2 SOLVED. For some reason you added the line <style amp-runtime></style> on your code a few months ago. I just searched for the line 109 and deleted (includes/vendor/amp/includes/amp-post-template-actions.php). Reference: https://github.com/ahmedkaludi/accelerated-mobile-pages/commit/411291e88a98a2f788ef381626c9afea36a7b306
Please help with the YOAST issue. Thanks!
