I’ve added summary_large_image cards to two sites and received approval for both. My metadata passes validation and looks fine. However, when I tweet, the entry appears with the 'View Summary" link, as though it knows it exists. However when I click on the ‘View Summary’ I just get a line and the same data I would see if I had clicked expand.
Here are two example urls for the two sites I’ve recently had approved.:-
Both URLs pass validation.
I even tried tweeting from another site that uses summary cards (not my own) and got the same result! Am I doing something wrong here?
