Upon insert or move of a feature I would like to call a service (using X and Y of the feature as input) and use the returned result for updating an attribute on the feature in question. This seems like something I should write an Arcade expression for. Apparently this is not supported for now.
I believe such capability is highly relevant considering Esri promoting the service-based architecture. Anyone out there agreeing, please give it a vote.
Esri - should you already be considering this please let me know of the roadmap.
