I have been unable to get the scoped_timeline endpoint to return any data when passing objective=VIDEO_VIEWS.
The accounts I am trying on have video player cards which were created natively, and can be promoted natively, but do not come back from the scoped_timeline?objective=VIDEO_VIEWS.
I understand that this objective is in closed beta, but our representatives have informed us that we should be able to pull this data.
EDIT:
2802227611 is an example twitter account, which has player cards.
