I built a web map which uses this vector basemap and is intended to be used offline. The offline function works with both envelope and polygon areas of interest. However, my client requested I replace the basemap with the World Imagery raster basemap which would be more useful to field workers. However, the polygon selection no longer works in the new web map and a rectangle is always returned.
The web map is downloaded by an ArcGIS runtime for iOS application following How to Take a Map Offline.
I have no explanation for the failure other than the switch from vector to raster. Is there another explanation? Is it possible to deliver both satellite imagery and polygon area of interest to my client?
