Hi Jennifer, we have not not seen this issue before. Can you tell us a little more about your situation?
- Do you ever see the a beta message and have a place to enter your story title? Or do you only see a grey background with a blue loading indicator (no text under the loading indicator)?
- How did you start building the crowdsource story? Did you try to share a webmap to the template? Did you create a new app from arcgis online? Or did you start from the story maps website?
- Are you in an organization in ArcGIS Online? What permission level are you?
- What operation system and browser are you using?
- Also, if you're willing can you send your browser console log (just upload it as an attachment). Below are instructions for Chrome:
Save Console Log
Open this URL: https://arcgis.com/apps/StoryMapCrowdsource/index.html?fromScratch&debug
Wait until the app stops responding (If nothing happens within a couple mins but the loader still shows, the app has stopped responding).
Open the JavaScript Console: View => Developer => JavaScript Console
Find an empty space in the console window, right click and the click "Save As."
Then upload this file as an attachment to your response.
