I've been struggling with this for ageeeees. We use ArcGis online to create webmaps that we can use for Collector and for the life of me I can not figure out how to enable any of the maps to be used offline.
I have followed the steps here https://enterprise.arcgis.com/en/portal/latest/use/take-maps-offline.htm
and use World Imagery for Export for the basemap. In ArcGIS online I have enabled the basemap and feature layers to work offline, but when I save and share and publish the map, then open collector on Trimble TDC there is just no option for downloading any offline maps. Perhaps I don't have the right license for ArcGIS to be able to execute this? I have a creator license and I am the administrator.
I need some help - it's driving me crazy, we work in heaps of areas with no reception and collector simply does not play ball in areas with patchy reception.
