Loading vtpk via VectorTileCache reports success but the map is not shown

Hi, I managed to correctly download a VectorTileLayer to a local vtpk file. When I try to load the map from the vtpk file, I get no errors (onSuccess is called on each load() procedure) but the map is not shown. Now, I'm thinking if I'm missing sth essetial. Here is my code.

fun loadMap() {
    coroutineScope.launch {
        val vtpk = "/StyleItemResources/myVectorTiles.vtpk"
        val externalFilesDir = context?.getExternalFilesDir(null)?.path
        val vectorTileCache = VectorTileCache(File(externalFilesDir, vtpk).path)
        Timber.d("Loading vector tiles from ${vectorTileCache.path}")
        vectorTileCache.load().onSuccess {
            Timber.d("vectorTileCache loaded.")
            val arcGISVectorTiledLayer =
                ArcGISVectorTiledLayer(vectorTileCache)
            arcGISVectorTiledLayer.load().onSuccess {
                Timber.d("vectorTiledLayer loaded successfully.")
                mapView.map = ArcGISMap(SpatialReference(MapConstants.EPSG_3857)).apply {
                    operationalLayers.add(arcGISVectorTiledLayer)
                    load().onSuccess {
                        Timber.d("Map loaded")
                    }
                }
            }.onFailure { s2 ->
                Timber.d("vectorTiledLayer load failed. Status $s2")
            }
        }.onFailure { s1 ->
            Timber.e("vectorTileCache loading failed. Status $s1")
        }
    }
}

Okay, my fault. I did not download the correct geometry and thus the map was empty at my current viewpoint.
