I have created a lightbox that links to a wistia account. It works fine but I can’t figure out how to set the thumbnail images that appears when the lightbox is open. It seems to picka image from the video. But when I change the thumbnail image in wistia for the video and change the thumbnail image in the webflow lightbox the thumbnail stays the same. Meaning the thumbnail image that appears when the lightbox is open are beyond by control.
