Using Portal 10.6 and its built in WAB which I think is 2.6. Trying to add a FeatureLayer to a 3D scene but getting the mentioned error that multipoint geometries are not supported. That's a bummer. Each record in this dataset has two points. Short of creating a new feature class and duplicating data that would need to stay in sync, anyway to tell the API to just plot the first point and ignore the other parts?
Thanks much!
