For the last 30 minutes all of our web map apps (web app builder and older templates) would not load properly. Only the basemap was visible. All of the map layers, widgets, title text, etc. would not load. The problem resolved itself after about 30 minutes. I have no idea what caused the problem or how it resolved itself. The health dashboard does not show any issues. Has anyone else ever experienced this issue?
The health dashboard is now showing a problem with the Hosted Feature Service cluster that has been resolved. Maybe I missed that when I first checked the dashboard or maybe it was added after I first looked. Either way I now know what caused the problem.
