How do I create a map that is view only that is also available offline? I am at war with this collector app. I don't need to edit, just view the map and be able to identify with popups. I can't even see the map if I don't have at least 1 layer that is editable in the map. We have areas in our system where there is no cell service, therefore can not be connected. NEED OFFLINE MAPS available! Please help!!
