I'm setting up several aggregators on a SharePoint Online site collection page that surface documents of the same content types from different document libraries onto a single page.
So far the Highlighted Content web part has been hit or miss, at best, so I tried using the PnP Modern Search web parts and they don't work any better.
For 2 content types using the query:
ContentType:"[content type name]
Works fine.
For every other content type it brings up no results.
I can find no difference between the content types. I've even created more content types using the same structure as the others and they aren't getting picked up by either the HCWP or the PnP-SRWP
How do I get these content types to show up?
