No "use offline maps" checkbox


On my 2013 Nexus 7, in DroidPlanner 2, in the advanced options section, there is no “use offline maps” checkbox. It simply doesn’t exist. Additionally, storage/emulated/0/DroidPlanner/Maps does not exist in the Nexus.

I have not ‘connected’ the Iris+ to DroidPlanner 2 ever yet. The Iris+ is not with me at the moment. Could this have something to do with it?

The use offline maps checkbox isn’t under Advance options. Go to:
User Interface
Map Provider Preference
Use Offline Maps
I found it stores offline maps when this is not checked.
