I'm trying to change symbology of a polygon feature service in my Map Viewer from one field to another (after I've hit 'Duplicate' on the layer) with the Counts and Amounts (Color) and Classify Data - 5 classes, Method Natural Breaks. It sits with a blue circle of death for a minute or two or five. Then -
Sometimes it works. Sometimes it goes back to the previous field and won't let me change the field that I'm using for the attributes. Sometimes I get the "The layer is not providing enough information to change the drawing style".

Help!
