Aggregate pages list other posts/pages like a catalog. In some cases, these aggregate pages (like blog pages) might not get automatically optimized when one of the posts/pages (like individual blog posts) is edited, or a new onе is published.
This happens when the aggregate page type is something different from "archive". A typical example is the "page" or "category" type.
You can find the type by inspecting the page's HTML with your browser's developer tools.
You can also see the page type in the Optimizations menu in your NitroPack account.
If you find an aggregate page with a type different from "archive", please note that it must be changed to "archive" for NitroPack to recognize a new post and clear the page's cache.
