Had downloaded and worked with it two days – Car Navigation: GPS & Maps Review

Got it to work on my 2018 f 150 with the normal download. Thought I would get the pro version and share the app with my wife. Cannot share it with my wife and can’t get to work on my sync 3 without navigation version. Can you help, really don’t want this to be a waste of money.
