I have created this "Snow Removal Tracker" storymap
ArcGIS StoryMaps
On the section "Thank a Plow Driver" I embed the page
https://data.orangeville.ca/Apps/SnowThanks/index.html
It works in all browsers except Edge (of course) where it doesn't load the iframe and the devtools cite
CSP14312: Resource violated directive 'default-src https: data: blob:' in Content-Security-Policy: ms-appx-web:///assets/errorpages/dnserror.html?NetworkStatusSupported=1#https://data.orangeville.ca/Apps/SnowThanks/index.html. Resource will be blocked.
It does show the iframe page in next section of the storymap with no problem
Dark Sky
Is there something I can add to the headers of my page to make it work?
I'm not sure how to remedy this, any help would be great.
