When a post does not have a featured image I see a mostly blank graphic, but sweeping left to right is a bar every 2 seconds. It’s very distracting and doesn’t look professional. Can we configure a default graphic for posts that don’t have a featured image?
For an example go to: https://www.derekseaman.com/ then click Next for a second page of top blog posts. Several will have the flashing/sweeping graphic issue.
