Using ArcGIS Assistant Beta v20250603.1, I copied a StoryMap from ArcGIS Online over to our ArcGIS Enterprise Portal (v11.5). The copy reported as successful, and all associated items appear to have transferred correctly.
However, when I try to open the StoryMap in Portal, it fails to load. After doing some digging, it looks like there may be known limitations or challenges when copying StoryMaps between AGOL and Enterprise—especially with newer StoryMaps built on the ArcGIS StoryMaps platform rather than Classic.
Any guidance or experiences would be greatly appreciated!
