Pop-up creates a link to a URL within an attribute in a layer. Once clicked, the link breaks automatically.

Hi all.

I'm having an issue with popups in an embedded web map that lives in a StoryMap. The webmap has a layer that shows sites that each have their own section in a StoryMap.

Within the layer’s attribute table, an attribute has been added for the StoryMap URL:

The links within the attribute table are used to make a pop up when the user clicks on a site:

Once the map is embedded within the StoryMap, something breaks and doesn't link to the correct location, leading to a death spiral. However, sometimes it DOES work, and we can't figure out what's going on.

Any advice is appreciated!
