Hi @BrittanyBurson ,
If your StoryMaps is publicly shared, feel free to send the link and we can take a look! It could be many things, but Owen mentioned permissions above because if it is only the map not appearing, it may be shared at a different access level than the rest of the story's content. If this started happening after an upgrade, there may be something else going on with the configuration after migrating that content to a new version.
I will note that the discussion above was for the ArcGIS StoryMaps builder. Were you all using that builder, or a classic Map Tour template? I know ArcGIS Enterprise had both available at version 10.8.1.
