I'm building a Story Map for my organization using the Map Series Builder. I've noticed that embedding my organization's web pages into tabs using the Web Page Link option does not work in Chrome, IE, or Safari. It only works in Firefox. We cannot limit our public users to only accessing this Story Map via Firefox. If there something about how Firefox handles web site security that is different that the other browsers? Is this potentially an issue on Esri's end? Please advise. Thank you! I am happy to provide the public URL for anyone willing to help troubleshoot this issue.
