Is there some extra settings for deep linking except the twitter:card meta tags?
I have set all the meta data, but when i click Open in X App, it always opens the app in Google Play store.
Btw, i just realized that my cards were changed on twitter for android, maybe it need little more time everything to become functional.
Another thing what i noticed is that Card validation on Firefox is not showing the right preview right, in Chrome works, but not quite right.
In documents https://dev.twitter.com/docs/cards/types/player-card
it says that twitter:player:stream is optional, and twitter:player is required.
When i test in Chrome, it shows the image, with disabled native audio player on bottom even the stream meta is not provided.
