I am currently working on a cascade story map, but at the bottom of every "slide" either a preview of the next image in sequence or a white block is appearing at the bottom of the screen. I have checked a story map created by a colleague several months ago, and the same issue is occurring. I created a test cascade story map on another Esri account, and the image preview/white block did not appear, which makes me wonder if it is something specific to story maps created within our organization account. Any ideas?
