Hard to Unsubscribe – 18Birdies Golf GPS Tracker Review

I like the app, but I don’t know if I have premium or free services. I followed instructions from 18Birdies, but I cannot find any way on the app to unsubscribe. I tried to cancel via the App Store, but no unsubscribe button appears. It should be easier to cancel.
