Unfortunately it doesn’t seem to work…
I use “Order by: Random” in case that makes a difference. I don’t necessarily need it to be random every time the page reloads, but I wouldn’t know how else to get a different selection of posts to show under each article. EDIT: Figured out using “No Order” instead of “Random” is probably what I want. However it still doesn’t limit the posts it shows to the ones with the “new” tag.
