Hi all,
ArcGIS Pro has this neat function "Enable symbol layer drawing" where you can define multi-level line symbols and set the Drawing Order to "Join" (all yellow line features are joined to look like one line)

vs. standard "No Join" (yellow line is interrupted with every single feature)

Sadly the "Join" setting is not transferred to AGOL when I publish the layer map. It seems not to exist in AGOL (or I just haven't found it?). Does anyone know of a workaround, e.g. via AGO Assistant? Or does the API simply not interpret this function? Here my JSON for reference:

Any hints are welcome.
Best,
Andrea
