Yep I can confirm fixed too.
New issue for me though. I can start a new thread if needed… The issue is that the wrong card type is displaying. We’re using meta name=“twitter:card” content=“summary_large_image”
It shows the right preview in the preview tool: http://cl.ly/Q42y
But in reality uses the standard small-image type of card: http://cl.ly/Q3SK
