Currently looking for work arounds to ESRI's StoryMap limitations on their Map Tour content.
Map Tour allows you to cycle through a list of points while displaying attachments, some attribute info, and of course where it is on the map.
You can also use an existing Web Map as a "basemap". The issue here, is that you cannot display the legend of that map while on the map tour.
Old StoryMap as discussed here could add the legend in the banner, but it looks like this is no longer supported.
Looking to see if anyone has come up with work arounds. I can of course add an image of the legend before the map, but that becomes inconvenient to refer back to as the Map Tour scrolls on.
