Activating 2 different cards (summary_arge_image) and (player)


I’d like to have player and large image with summary cards on one website. I’m not a developer and our part-time developer doesn’t know anything about twitter cards.

Right now I have the Large Summary card turned on via WP Yoast app. Most pages work, but some of the main landing pages do not.

Would anyone be able to help me with code to get these working?
