Hi

We have added cards page example: http://www.extensions.sashas.org/questions-and-answers.html but there is no request for approval button in the validator.

Thanks

Hi, I have tried to validate the summary card for the URL www.salzburg.info/de

the following code is integrated in the meta tags.

The validator is unable to render the Card preview and I get the WARN: Not whitelisted.

What has to be whitelisted and how to do that?

Thanks
