I have created a hosted feature layer from a geodatabase with a single feature class that I created on my desktop and uploaded to ArcGIS Online. I was able to create an Explorer Map using this feature class and publish it, however when I clicked "Enable Attachments" and attached the images to each point, the images do not appear in the story map and when I go to publish it, I receive a "Sorry, there was a problem publishing your story map" error. I've tried a bunch of things such as deleting the story map and re-creating it, attaching the same image twice each point (I heard that one is used as the thumbnail and one as the media image). These images do appear in the popup when I put this layer into a web map or map on ArcGIS Pro.
