Not valid Structured Data, therefore useless

If you just want amp pages generated to look at, it works. But if you test the Structured Data output at Google at https://search.google.com/structured-data/testing-tool it fails – you can have an image on the AMP page but the plugin has failed to include that in the Structured Metadata it generates for the page.

You’ll then get messages from Google Webmaster Tools / Search Console telling you the page is not valid. More importantly, for Google’s purposes it then has no hope of getting treated as AMP and getting into their news Carousel. Since most people would install it hoping to get that placement, the plugin is useless in its current state. Needs work.

Also some CSS configuration would be nice – currently you need another plugin for that.
