Twitter doesn't show preview image

Hi folks. Bit of a conundrum.

• Two Blog posts
• Both have the same teaser image
• One has an image in the post body
  (https://community.spotify.com/t5/Spotify-Community-Blog/The-Tip-Off-Mega-Ran/ba-p/1423394)
• One doesn't
  (https://community.spotify.com/t5/Spotify-Community-Blog/The-Tip-Off-PAUW/ba-p/1482837)
• Both have very similar metadata (twitter and OG), yet, the second one, when posted to Twitter, doesn't show an image

Sample data from both posts' source (I truncated some of the content to fit better).
