I have a StoryMap with Map Tours. Data for Map Tours are called from a Feature Service that contains a field for "Narrative" which was created from a calculated expression to display in html. Media are images attached within the Feature Service. All displayed on a custom basemap.
All images in the Map Tour display just fine when viewing the StoryMap (Normal behavior.png) as it's own application. However, when opening the StoryMap from the HUB page within our HUB site, the images do not display in the Map Tour (viewed from HUB.png). I've tested different Map Tour styles and none display the Feature Service's attached images.
