Description of issue:
My video isn’t playing properly in the Player Card and I can’t figure out why. (Where the video should be playing, I see a white space)
URL affected (must be public):
Troubleshooting steps attempted [note that we will not prioritise posts unless there is evidence of following the troubleshooting guides]:
The URL specified points to a full website, not a page that fits in an IFRAME. The value for twitter:player needs to be a simplified web page with only the player on it. Having a full website will show only part of your site in the Player Card IFRAME.
This has been done - albeit after whitelisting.
The dimensions of the Player Card aren’t specified. Be sure to include the twitter:player:height and twitter:player:width tags with your Card tag.
This has been done.
The video format is not supported.
The video is mp4 - a supported format.
