I got email from Google after update this plugin:
“Increase in the number of non-valid AMP on [my blog]
To owner of [my blog],
Googlebot has noticed a significant increase in the number of invalid AMP pages on your site. This may indicate a change in your AMP implementation. Pages with severe errors might be shown in Google Search without AMP-related features. The linked report provides examples of pages with errors.”
The issue is “The tag ‘script’ is disallowed except in specific forms.”
