Facebook friends search returns with no results

Hi, I can successfully call the function Cloud.SocialIntegrations.searchFacebookFriends but it does not return any friends. This is what I did:

• added my app to developers.facebook.com
• added a test user on Facebook who is already a friend of me
• for my developer account and the test user: Called Cloud.SocialIntegrations.externalAccountLogin with permission 'read_stream'
• called Cloud.SocialIntegrations.searchFacebookFriends

The resulting list is empty. Any suggestions?

Note: I got a message "Some of the permission low have not been approved by Facebook" but I am unsure if it has something to do with it since the Facebook app is still in developer mode this is normal.

Also, I read some posts that the function only returns first 10 results and the option to increase this is missing. Is this still true?

facebook.permissions = ['read_stream','email'];
 
    Cloud.SocialIntegrations.searchFacebookFriends(function (e){
        if (e.success) {
            console.log('Success:\n' +
                'Count: ' + e.users.length+' '+JSON.stringify(e));
        } else {
            alert('Error:\n' +
                ((e.error && e.message) || JSON.stringify(e)));
        }
    });

result:

Success:
[INFO] :   Count: 0 {"users":[],"success":true,"error":false,"meta":{"code":200,"status":"ok","method_name":"searchFacebookFriends","page":1,"per_page":10,"total_pages":0,"total_results":0}}
