We are early adopters of AGOL and have 100's of Web Maps and Services hosted on AGOL.
So we have some experience / methods for navigating "enhancement" pushes to the system.
Unfortunately, we can't figure out an issue with Mixed Content in Story Maps within AGOL.
The issue is when a Story Map has mixed content, portions of the Story don't load or prevent the App from loading at all.
My understanding of mixed content is having sources to http & https within the same App.
We're aware of the settings in AGOL under security that reuire SSL.
We don't require SSL.
Should all content in a Story Map be http or https?
Because having both does not work.
For us this means searching through 100+ maps to ensure they all work or are free of mixed content.
We're searching for a path forward.
