Facebook real time updates push on story remove, but not on story add

I am using Real Time Updates in my application. I am subscribed to the User->Feed subscription. All facebook accounts connected in the system have permissions of offline_access, publish_stream, read_stream, and manage_pages.

I am receiving updates when comments are posted to existing stories on a users wall, a开发者_运维百科s well as when stories are removed from the wall. But when someone (not using my app) creates a new post, directly to the app users wall, I am receiving no update from facebook. Even stranger, if the post is removed, I DO receive a Story/Remove notification from facebook.

How can I get facebook to notify me when a new post is created on a users wall? I have tested this multiple times with different accounts to no avail.
