I'm having an issue with the ArcGIS Enterprise 11.2 3D Scene Viewer Instant App. I've configured it with the Navigation Toggle Controls and Zoom Controls. I save and publish. When I launch the app, I see the tools load for a split second, and then they are gone. This makes my CAD to GIS Digital Delivery demos slightly interesting when I'm trying to navigate around. The value of this app is the slice tool and the measure tools for doing design reviews.
