I'm trying to migrate information from a classic story map to ArcGIS StoryMaps - specifically a slideshow with separate express maps in each slide. I have full functionality to add points with a title, description, photo, etc. within one slide/express map, but as soon as I add a new slide and choose to add an express map I can no longer edit the prior map/slide except to delete points I had previously added or add new points but not be able to rename/add photo/description. This map is intended to show on-going developments and would need to be updated often so I'm not sure if this is just a glitch or perhaps not the best option to build my new story map in.
