It seems there is a bug (syntax error in a js file) in the StoryMaps application with Iphone iOS 16 as you can see in this capture
Thank you!
Has this ever happened before or is it a new StoryMap you published?
It might be worth having a look through the following community post on this error message you are getting:
You should be able to access the JSON either via the web traffic or using AGO Assistant.
Has your StoryMap been deleted?
The storyMaps is 100% functional on android device or desktop. The problem seems to be in the application code.
