Summary card with mobile app tags not working


#1

I got approved for summary card and the tweet works but shows only title & summary.
Image & mobile app links are not visible. What is the problem here? Do mobile app tags work only with App cards? What about the image for summary?
I tried using validator tool for app card with my live app but it says “Unable to render”

Sorry for the delay. Can you change your twitter:image to point to a larger image – min 160x160?
