On one section of our site, we switched from responsive design to an AMP-default (page is AMP with a desktop responsive version).
This section auto-generates thousands of product pages, when a page has few results (low quality page), we block it with a meta robots noindex.
A valid AMP page must have a canonical tag. And Google has repeatedly recommended not to use canonical and meta robots noindex tags on the same page.
Also, adding a noindex tag to AMP pages triggers a warning in GSC.
So, we how do we block the low quality AMP pages from Google's index?
