I have a persistent issue where map viewers fail to load after the initial opening. So if I open a browser and go to the web map it is fine. If I leave the web map and then come back to it later it is just a blank white page. No helpful errors or warning messages. I can get the issue by opening the map and then just refreshing it.
I look at the developer console and it says "Uncaught (in promise) TypeError: Cannot read properties of null (reading 'insertBefore')".
Has anyone experience this issue? Is it a browser issue? Or does it have to do with our enterprise deployment?
Further to this... it seems that the issue could have been one of the Edge Extensions. Initially, it appeared like the Bitwarden extension was causing the problems, but after enabling/disabling the extensions everything seems to be resolved now?
