Plugin seens not to work properly

I tested this post as an example – https://www.schneesportlehrer.biz/2017/11/28/685/

I do see everything is configured properly. And it shows up perfect in Twitter Validator – https://d.pr/i/rMpvs7

thank you for your reply.
yes validator shows up perfect. but in twitter i only see the link as text. even from another account.

username @snowbolzer

any suggestions?

Here is a screenshot of your account, it’s showing the Summary Card – https://d.pr/i/jMrLBN
You have configured it for Summary Card, and that’s what you have now.

Thank you again … can‘t see it this way if i search in twitter
