According to the FQL Stream documentation the following query is supposed to return impression counts when run by an authenticated page owner, yet it never does. We have the page owner authenticating directly in the graph api explorer with extended permissions (read_stream, read_insights), but the impression counts are always null.
Is anyone able to get this working?
SELECT post_id, actor_id, message, impressions FROM stream WHERE actor_id = {owned_page} and source_id = {owned_page}
