I am using SSO in my application, and I see my application in Facebook for iPhone “Apps” section, and when tapping on it it launches my app. This is normal and works perfectly. Now, when I use a feed dialog on my App to publish a feed story, I do not see the App Attribution next to the “via APP_NAME” like I should. I also marked my app as “SSO enabled” in the apps settings.

Do you have any idea why it’s not showing up the little icon to launch my app on the iOS device?
Thanks a lot
After facing the same issue i finally got it to work. You need to make sure that in your facebook app settings you have set the “app namespace” under the “Basic Info” section. After I’ve set it, it took several minutes to propagate throughout their servers but then it worked for all the stories published by the app.
