My StoryMap is a split screen with a map on the left and content scrolling on the right. It is published and pretty much ready to distribute, but when I scroll through the published version, the images sometimes jump or skip or stagger instead of the scroll being smooth and continuous. This seems to happen more often when there are two images back to back or a video and image back to back, and potentially when an image is on the larger side (though there are examples that are exceptions to those cases). I tested the StoryMap on three different devices and it does the same thing every time. Is there a reason why this is happening? If so, how do I fix the issue.
