Feature services, which were previously created and visible, are no longer visible in ArcGIS Online. They were created using an ArcGIS Online for Organizations account and are no longer visible inside or outside of that account. The map will zoom to the area of the service, but the symbology and pop-up are not visible.
I have looked at a number of feature services, created by a number of users, in the same way and none have been visible, except one which is a point feature service. However, another point feature service, created by our Esri account manager, is also not visible.
Am I missing something or is there a system-wide issue going on here?
