Hello!
We got message from Twitter, that our player card was not approved. We double checked in with validator and got all green dots.
Can you please provide us with more information on the issue?
Sample card can be found on the page http://ldpr.ru/events/videos/ldpr_rally_on_pushkin_square_23022014/
And the player link is https://ldpr.ru/video_embed/?video_id=70845
Hi @ilyashuma, Your submission was not approved because the video does not play on mobile devices. The experience must work within all Twitter clients including twitter.com, mobile.twitter.com, Twitter for iPhone and Twitter for Android (https://dev.twitter.com/docs/cards/types/player-card) Once these issues have been resolved, please resubmit your Player Card to our validator (https://dev.twitter.com/docs/cards/validation/validator).
