We're creating a Story Map with ArcGIS Story Maps, and everything was working fine until today it seems; now, whether viewing the Story Map in Chrome or Edge, certain web maps will not display. Or, they'll display after clearing your browser cache upon first load but then disappear after a while. The behavior is the same whether editing or previewing the Story Map. I'm guessing it's related to the update esri pushed a few days ago? Is anyone else having this experience, and have you found a workaround? I'm wondering if it's related to if the web map was authored in Classic Map Viewer or the new one, but I haven't tested it fully to know for sure.
Example screenshot of what I mean attached.
*** EDIT: If you're experiencing this too, please see the post linked below and contribute responses there. I messed up and made one in two different Communities. ***
