I published our draft StoryMap to test it on mobile, and while it works on my iPhone and a friend's Android, it won't load for another iPhone I tested (iPhone 6S, version 11.2.6) — we simply see a blank white screen. That's for both Safari and Duck Duck Go browsers, with cleared browser caches.
Here's the StoryMap: https://storymaps.arcgis.com/stories/4d5321c2be8e4188ac175228763021f2
How widespread do you expect issues like to be for mobile viewers? Any ideas about what might be going wrong?
Second, what should we do to make our StoryMap more mobile compatible (in terms of image sizing, immersive element use, etc.)?
Thanks!
