I'm currently working with a few different tabbed Story Map (Map Series Tabbed). Up until about two weeks ago they were working fine, but now I've noticed that when I open them several tabs will not display their legends. The legend panel will appear, but it will be blank (see attachment). Navigating to the next tab in the story and then immediately going back will allow the legend to display.
I did have a phone call with ESRI Customer Service and the technician suggested I try deleting the first tab and re-adding it. I did try this, but it did not work. It should be noted that I only deleted the tab, not the map associated with it. The data displayed on the each map is a mix of Hosted Feature Layers and zipped shapefiles that have been uploaded.
Does anyone have any ideas on what I can do to get the legends to display properly upon opening?
