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?
