I am using the new Map Viewer and Arcade Expressions to define the symbology styles for a polyline layer. Once I apply the arcade expression, only the labels within the active map view are shown in the "Styles options" page. This only allows me to be able to define the color and width of these specific labels. I then have to find the features in the map to have the labels show up to be able to be defined by color and width. Is it possible to force the map viewer to show all labels defined in the Arcade Expression? Also, is it possible to define the color and width of the style in the Arcade expression?
