I've created a feature layer in ArcMap and put it on my map. I can collect data in the field with Collector and it syncs up perfectly to my ArcGIS Online map, but I cannot add a point and input data from ArcGIS Online. When I go to "Edit" on the online map viewer, it allows me to edit existing feature points, but when I try to add a new point, nothing happens. I am the administrator and all permissions seem to allow this. What am I missing?
