I have a presentation tomorrow that I've been making a story map for, and realized the place of the presentation doesn't have wifi. Is there a way to download my story map and show it offline?
Currently story maps do not support offline usage. To use your story map, your end users need to be connected to the Internet, or to your enterprise network in the case of Portal for ArcGIS. Perhaps you can get on cellular network?
If your presentation is not specifically about your story map, you could take screenshots of your story map and put those into Powerpoint slides. It can be just as effective as showing a live demo and your audience can try the live link themselves later.
