Using this also removes all the featured images from responsive version for mobile users. The mobile version displays all the posts in a list, with the image and a title, and using this just creates a list of titles, that’s not good for mobile users.
I really need to remove this pointless featured image from posts, but want it to remain for mobile users, and I cannot find a solution to this anywhere.
It also seems that a lot of people are still not thinking about the massive mobile market, using this method of removing that line without checking the impact it has on mobile viewers.
