Enterprise 11.2.
In the Experience builder edit widget I have my editing values setup via symbology. I've included a value that doesn't exist in the database because some of the values like zonings fluctuate. The edit widget is not picking up these values.
So you added a new one that hasn't been symbolized yet? Did you give it a symbol in map viewer so it shows in a a legend? Did you remove the layer from the edit widget and re add it?
