FBSDK findByGraphPath (me) doesn't return an email, even with permissions and explicit fields

Question

I try to fetch at least id, username and email from a logged in Facebook user. I first login using the permission type: Email. And if succeeded try to fetch an FBSDKGraphRequest, which returns every possible value but email.

I tried adding permissions like public_profile as well, but in any case I try, I do not get email. I looked in the developers dashboard, and email seems to be approved by default.

FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
[loginManager logInWithReadPermissions:@[@"email"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
    if (error) {
        NSLog(@"Error: %@", error);
        return;
    } else if (result.isCancelled) {
        return;
    }

    FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, gender, first_name, last_name, locale, email"}];

    [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
        if (error) {
            NSLog(@"Error: %@", error);
            return;
        }

        NSLog(@"Fetched user: %@", result);
    }];
}];

I just had the same problem and I was lucky enough to find the solution in the comment. It is given by CBroe. I think that this should be posted as an answer.

So... in my case the problem was that the user had not confirmed his email. Once I've confirmed it I received the email from Facebook. All the acknowledgemnts are to CBroe
