Our player cards are working fine, but in the iOS and Android native apps, the application does not load the media stream from the twitter:player:stream url.
Instead it links out to the twitter:player url.
Here is an example stream url: https://d2ypmjob883gxf.cloudfront.net/6/466/p17vj8oo4l1o4a1il442d12p6e9g5_480x270_400.mp4
Why would this be happening? We are following the docs guidelines exactly.
