I'm unable to load or build a story map (Map Series) in Internet Explorer 11. I built one in chrome but I still cannot launch the application in IE. Is this a bug? This is on Portal version 10.6.
The original poster elected to use the Swipe Widget in a Web App so may not have found a resolution for the initial issue.
I'd suggest continuing to further investigate with Tech Support
We recently upgraded our Portal to 10.6.1 and it appears the story maps work in IE 11 now. My current IE version is 11.706.17134.0.
