Is it possible to use Bing Maps in the offline mode in the ArcGIS Collector app? In ArcGIS collector can I download the map, work offline and sync my edits when I'm using Bing aerials as my base map? I know that this is possible when using ESRI published aerials and base maps but what about Bing Maps. I have tested this and I don't have the option to download the map for offline use when using Bing Maps but I'm wondering if there is something I'm missing. I already have the Bing Key registered and setup for use in my organizational account so that's not the issue. Has anyone had success using Bing Maps offline?
