Dear @AbbyE_Esri and @OwenGeo
I am currently solving the same problem with a customer that is described in this article.
Previously everything was fine, they just needed to add a few maps but suddenly it stopped working.
The Storymap status is still as draft.
In other Storymaps this same data works.
For one particular Story Map, they cannot open its editing. They can only show a preview.
They have tried copying, and ArcGIS Online Assistant tools (both, PS and normal).
They have tried another browser and deleted caches and cokies
None of this has helped so far.
I am now taking the case up with Esri Technical support, of course.
But since it is very urgent, I would appreciate some quick advice if there is any way to fix it.
When we don't have the possibility to download Draft JSON.
Unfortunately I can't think of another way to fix the story. We know from the past that communication within the Community can be very beneficial.
The customer would really hate to create the story again. Not much time for that either unfortunately.
We would be glad for any help here as well.
Thank you.
Sincerely,
David "Dave" Novak
