Bad decision to get this extortion app – Avenza Maps: Offline Mapping Review

Both my wife and I got this app in order to use the maps for Tennessee state parks. It worked ok at first even though the maps are basically a joke. I purchased maps for several state parks we wanted to visit. A year later the app no longer works with the maps we already paid for and demands we upgrade to a $30 a year subscription service. I will be registering a complaint with Tennessee State parks and with Apple on this bait and switch app.
