In AppStudio-Apps KML-layers of webmaps are not shown in the Map. Any idea why?
KML is not yet supported in ArcGIS Runtime, which is what AppStudio is built on top of. Hence, this is not working in the web map you are viewing in AppStudio. We are adding KML support for the ArcGIS Runtime Quartz release, so once that is released and once AppStudio is on this version of the runtime, this should begin to work. It is a known limitation in the meantime.
I'm not really familiar with AppStudio, but at least for the web map APIs, I know that KMLs must be public/forward-facing.
