Hi There,
Just recently I had a Story Map become corrupted (https://community.esri.com/thread/208332-adding-a-webpage-as-a-new-tab-corrupts-the-story-map ) and it would have been really useful to have the ability to go back to working version. It doesnt have to be full on versioning just the ability to go back to the previous version so that if this happens at least as a user you can go back.
Cheers
Andrew
