Hi there
After working through the Load a Web Map and Display Device Location tutorial, I tried to add the ability to observe the device location onto a scene view but I get the error that locationDisplay is an "Invalid property name "locationDisplay". Taking a quick look at the API reference (LocationDisplay QML Type | ArcGIS for Developers ) it only mentions its use in a map view and is silent on whether it can also be used in a scene view.
Have I missed an important step or is a very different process required to observe position in a scene view?
