We’ve submitted a Player Card for review, however we’re receiving this response for our rejection:
Test your experience across all Twitter clients, including Twitter’s iPhone and Android apps, as well as twitter.com and mobile.twitter.com. Cards that do not work in all Twitter clients listed will not be approved. Your card loads on iOS and Android, but not on desktop.
The link used to test is http://www.mobcrush.com/videoshare/547d7109d2b0bb3d07d8e967. It looks like the Player Card works fine on the web for us. What else do we have to do to get the card approved? Thanks.
