My Collector for GIS App is installed on my Samsung Android tablet. I have downloaded a map to use offline with a custom base map but when I tap on the map I get nothing but a spinning circle. What could be some of the causes of this problem?
Your best bet for getting this one answered is to ask it in the https://community.esri.com/community/gis/applications/collector-for-arcgis?sr=search&searchId=398ff7... space.
I have the same problem. I have tried opening the maps on Windows and iOS devices with no issue. However, any android platform will not work.
