We are using a map that has a tiled image service as the basemap. It's on our own server, published with 10.2.2 with the option enabled to allow exporting. On the device, the download icon is available, and we can click on it to select the area to download. However the success stops there. Usually you get the little toggle at the bottom (Work Area/Map Detail) but that is not present. You can click on the "Download" link at the top right but nothing happens. This has worked fine with our tiled map services, so I wonder if the fact that it's the image service is the problem? I cannot find anything in the documentation that addresses this.
