I have a problem with the visualization of a video embedded from youtube in a landing page using this marketo's guide (i need to track the video): http://developers.marketo.com/blog/send-view-data-from-a-youtube-video-to-marketo/
My problem is that at the beginning i saw the video in all the browsers (Chrome, Firefox and Explorer). Now i see the video only in Google Chrome.
Why this is possible? How i can fix this bug? There is another way to embedded the video so that it is responsive?
You always need to provide the URL of your page when asking Qs like this.
