title: 'Use of app has been restricted'
body: <p>When users are routed to my Facebook application without being logged in first, they receive the error "'Use of app has been restricted.' I have tried the different URL trick (as has been suggested before) but it doesn't seem to work. HTTP and HTTPS are enabled, Sandbox mode is off. The app is restricted to individuals in the United States and 18+ but I don't think an issue with that would produce the same error. If anyone can provide any assistance, it would be greatly appreciated!</p>
