Also, if I go to page 2 of the category archive, will it default to the standard archive or still use the static page?
Ideally what I’d like is the first category page to be a static page with the WPSP in it. (Possibly the WP 5.8 query loop in the near future), then the pages 2 onwards for that category, to use the standard WordPress archive
Or, I can have a different static page for page archives 2 onwards, that would work too. Basically I want the first page of the category page to be different from the pages 2 onwards
