It seems like this should be easy, but I do not see an option to exclude the featured image from the category index pages, or posts index pages (whatever they are called). Here is an example of the page I'm referring to: https://wp.oldmagazinearticles.com/titanic_history/
You see, there are multiple featured images, one for each article, however we just want to list of articles, no featured images.
I've looked through all the settings on WordPress and the Asta there, which we are using, and did an internet search. I find articles to remove feature image from the individual posts, but not the post list pages.
Any help would be nice.
