I am developing a story map series with multiple tabs. If I use the builder to add any type of hyperlink in the text panel (e.g., change main stage content or open another tab within the story map), the application will not save (i.e., I get a "Save failed, please try again" message). If I remove the hyperlink, the story map will save. This is severely limiting my ability to create an interactive story map.
I answered my own question. It seems the problem is browser specific. When I switched from Chrome to Internet Explorer, the "Save failed" message did not appear.
