On my Ipad I have created a TPK which I used as a base map for my downloaded maps on COllector. The basemap was side loaded a while ago using Itunes.
My Ipad recently had a major update - going from Version 9 to Version 11.
Now when I use Collector to download a map onto my device, I can see my basemap TPK in the Choose Basemap section, however when I click on it to choose my work area nothing appears - just a blank square, so am unable to download a map (see attached photo)
Has anyone had this problem before and is able to suggest possible workarounds?
