I need to use another app in the field at the same time. So I did switch over to the other - so if that means shutting it down, then yes, I did. But if your app is supposed to work offline in the field, a user should be able to access their offline material...
I purchased an iPad mini specifically for using this app in the field, spent a zillion hours learning how to make maps that will actually download, spent a zillion hours making those maps, and now I cannot use it. I tested this system on my personal iPad, while offline, and it worked. I did go into and out of the app while offline during this trial. So I based the new purchase on that trial. But when I purchased the new iPad and tried to use it, it does not work, and signs me out. I hope you can help me.
