Missing allowfullscreen tag in iframe



I am not able to view the video in full screen when I share a player card. I checked the iframe configuration and found that the iframe is missing allowfullscreen attribute. Is there any setting in twitter cards to enable this option?


Fullscreen for Player Cards

Same problem here; it was working some days ago!


What is the link you are posting to Twitter? It seems that Twitter is putting some users iframes in sandbox mode. Sandbox mode could be blocking ‘pop-out’ features of the iframe (such as full screen mode).

Check the forums, there is a lot of activity going on now about Player Cards not working correctly.



Yes it seems that they remove the allowfullscreen tag and add the sandbox one at the same time…


I am not sure why it has been removed but it is must feature to have when we are using iframes.
