I created a Facebook APP for my website. I sent the APP for reveiew & I linked the APP from my facebook page. But something is missing. When someone visits my APP they get taken straight to my APP page without the usual "install this app" request.. Meaning my APP is operating as a sort of webpage rather than an APP. How do I set up my APP so that people have to install it in order to play it ? And so that my APP shows up in their "App centre" on their profile ?
