I have a web based app that sometimes send notifications to users using the following:
$response = $facebook->api('/'.$userId.'/notifications', 'POST', array(
'template' => 'A template here',
'href' => 'link-here',
'access_token' => 'part1|part2'));
It works as expected and the users get the notification if browsing Facebook in a browser however the notification does not appear in the Facebook app on iphones or any mobile devices?
Why is this, have I missed a setting in the developer setup?
