My site, http://jim0thy.com, was approved from Twitter Cards in November. They were working fine up until Feb 6th, when they suddenly stopped.
Is there any reason why this would have happened? The preview tool shows the cards okay, I don’t think it’s a problem with the meta tags.
Do sites get unapproved for any reason?
Edit: Here’s a link to a tweet that should have a card but doesn’t: https://twitter.com/jim0thy/status/307487244657233920
