Cannot login with Facebook on iPhone app

I downloaded the iPhone app and tried to sign in with my Facebook account. I accidentally hit the do not allow sharing button which I guess means the sign in process cannot start with the FB ID.

However when I try to do it again, the FB button does not activate and the app is hanging. I tried to delete, reinstall but does not seem to help.

Go to your iPhone settings and open Facebook settings. Under "Allow these apps to use your account", change the entry for Duolingo to the "on" position. If that doesn't work, removing your Facebook account from your device and adding it again will also fix the problem.


I still can't login on my iphone with my FB account :(
