Currently - Flow can only track facebook timeline post that was posted by the owner. New Idea 1 - Flow to track anyone who are allowed to post to the owner's Facebook timeline. I think this one makes more sense than tracking the owner's post to his own timeline, don't you think? The objective is for flow to track what anyone post to one's timeline. New Idea 2 - Flow to track any comments made by anyone who are allowed to post comments to the owner's certain posts.
