I used to AGOL Admin tool to change the URL Key of my organization. After this change, all apps made with the Web App Builder are no longer functional. The app attempts to load, then gives a blank screen. All other services, web maps, and interestingly, apps from the generic templates DO work.
My inkling is it has something to do with app registration, but I’m not sure. None of the WAB apps were registered.
Can anyone shed light on why a URL Key change would break all WAB apps? And, if my problem does relate to app registration, why do I need to these apps registered to use them after a URL key change?
