Hello!
I have set up a public ArcGIS Experience on my company's AGOL for a particular client. Both of the users on the client end were experiencing issues where the widgets and header would load when they go to the link to the Experience, and they were getting the "creating map failed" error.
I had a meeting with them today and the issue was resolved for one of the users, but one of them is still experiencing the same issue. The only other post describing a similar issue was resolved by updating the sharing settings, but this does not apply here as one of the users is able to view the web app anonymously.
I've attached a screenshot of the console log from the user experiencing the issues. Is anyone from Esri able to provide some insight regarding why this issue is occurring? The user who is no longer experiencing issues did say that there was a Mimecast window that appeared when opening the link, and then it opened correctly. Apparently this window did not open before and they were getting the error so could this potentially be the issue? The user experiencing issues would also have Mimecast installed and stated that the window does not appear and then they get the error.
Please let me know if I need to go back to the user and get them to export the entire console log, or if what I have provided is enough to identify the cause of the issue.
