I found it impressive to use the new language Arcade, for symbology or labelling in ArcGIS Online / Portal.
We have now the following problem:
If I create a symbology depending on 2 fields and concatenate them to one value for symbology with Arcade, the symbolgy disappears in the map and feature tempate and nly a black point is shown!
Our feature service has its own feature template from the concateneted fields, but if editing the created symbols (markers) are not shown?
Does someone has any ideas why this happens?
