Why I can't show twitter cards on a tweet?


Why I can’t show twitter cards on a tweet with this link http://selbstbestimmung.ch/wissenschaft-technik/accessibility-apero/? The site is valid for twitter cards.


i have same problem


I am having the same problem. Does anyone know HOW long before the newly validated twitter cards will reflect in the tweets? I just need some idea of what Twitter’s time frame is or to determine if something else is wrong. ??? Why haven’t we heard from a Twitter rep on this post yet?
