Twitter player card rejected by email for the following reason:
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 doesn’t load on any platform. Please check your meta tags. Testing instructions are available here: https://dev.twitter.com/cards/types/player#Testing_your_Card
But I have tested the twitter:player url in all the supported clients (android and iOS devices) with no trouble according to twitter instructions in the url mentioned above.
According to the email they are unable to load the card on any platform so I can’t figure out what’s the problem. Any feedback on this would be greatly appreciated.
The card is audio only and specifies the twitter:player url only. One example of the card is shown in the following url https://hyhy.co/p/gLD.MT
The card validator output (which show the card correctly):
