Their policy team has explicitly approved this category of pages three months ago. Recently we got a policy note about two of these pages (there are millions).
Millions of pages...sounds like you're either really busy generating this content or it's user generated. If it's user generated I'd be surprised if it's just two pages that are being flagged. More likely it's just those two pages that Google is using as an example to show you the violation in their policy note.
