Here are the two pages that the Google Search Console shows 2 Critical Errors for: 1. https://www.hillwebcreations.com/fix-product-markup-errors-avoid-google-manual-action/amp/ 2. https://www.hillwebcreations.com/google-image-guidelines/amp/
Both (out of 80+ post are the only two with issues all use the exact same AMPforWP plugin) show the same 2 issues:
Details:
(1) The mandatory tag 'amphtml engine v0.js script' is missing or incorrect. (2) The mandatory tag 'link rel=canonical' is missing or incorrect.
But then when I run the link to the AMP TEST, both say "Valid AMP page Page is eligible for AMP search features in Google search results".
And oddly, the one URL has a strange "v" added to the end. Where does that come from?

Thanks in advance for any help to sort this out.
