Summary tags are correct, page is whitelisted - but no cards preview

[so_phies]

I am trying to get the summary cards to work with our page express.de. I have been in contact with the support which send me here:
“I do see Summary tags on that link, and can confirm that express.de is whitelisted for Summary Cards. As a next step the best place to seek technical support for this matter is in the Cards developer forum.”

On the cards validator the page is still not whitelisted and I cannot apply for approval:

HELP!

Best,
Sophie

Hey Sophie! I’ve just tried validating another one of your pages, and a card preview shows up. Are you still encountering this issue? If so, can you share a link to a page which has an issue?

(note that you don’t need to apply for approval for summary cards, just make sure the markup is correct)

Oh, you are right! They started showing up yesterday after weeks of troubleshooting!
