I requested twitter player card approval for several times and unfortunately failed.
Here it goes the message from twitter.
We can make it work. Let us explain.
The URL you provided for social.marketkarma.com 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!
I checked the meta tags again and again and even tested on validator(https://dev.twitter.com/docs/cards/validation/validator).
The validator says it is valid.
This is the sample video url from my site.
Would you kindly advise me on how to make things happen?
I will be waiting for your kind help.
