I've got some problem with the login flow. When a user click on login button he's redirect to the permissions flow. If he accepts, there are two ways :
- no facebook app installed : everything is good, the user is redirected to my app
- facebook app installed : an error is returned.

As you can see, the app pic is empty, I don't know if it's a clue. I checked my bundle id, it's ok in ios side and facebook side.
I tried to login in different way, with FBLoginView, with
[FBSession openActiveSessionWithReadPermissions:allow LoginUI:completionHandler]
but always the same error with the facebook app installed.
I really don't know where I failed.
