I have a developed a StoryMap that has an embedded Web Appbuilder App.
The URL for the Story Map is:
The URL for the Web AppBuilder App is:
The Web Appbuilder app has popups that allow the user to pick from a series of pre-formatted PDFs. The popups work fine from the Web Appbuilder app when using Chrome, Safari and Firefox.
The same Web Appbuilder app is embedded in the Story Map... When using the popups from within the Story Map, everything works OK in Safari and Firefox, but Chrome seems to think there is a problem with the server hosting the PDFs, and doesn't display them.
I'm stuck as to why Chrome seems to have an issue with this?
Grateful for any suggestions.
