Received this email:

The URL you provided for crossfader.fm to use the player card did not validate. Please make sure the page contains valid metadata, then reapply for a Twitter card.

Thanks for your patience. See you soon!

Can someone help explain what’s wrong with my metadata?

Hi @CrossfaderApp, The pause / stop controls on your player card do not work on web. Once these issues have been resolved, please resubmit your Player Card to our validator (https://dev.twitter.com/docs/cards/validation/validator). Should you need to discuss further feel free to create a ticket at https://support.twitter.com/forms/platform
