YouTube has made a change to the protocols allowing third party applications and browsers to connect to, and embed, its content. ActivInspire can no longer play YouTube videos embedded in a flipchart, so you will see the following blank object when you insert YouTube embed code.
Promethean's development team is aware of the change and is investigating how to make ActivInspire compatible with YouTube's new protocols.
To link to a YouTube video from your flipchart, go to the Insert menu, select Link and then Website to create a link to the video on your flipchart page. Clicking on this link will open the YouTube video in your default browser.
