I built some web maps and symbolized some point features using an arcade expression. The count & amounts symbology works great when using a desktop browser to view the maps. But both explorer and collector fail to render the points at all unless i change the symbology back to more basic type. Is this a bug or a limitation for now?
It is a limitation at the moment, work is ongoing to get it working for a future release.
To be a bit more clear... the use of Arcade for symbols is not fully supported in the ArcGIS Runtime that Esri Apps ex Collector, Explorer, Navigator etc.. are built on.
