Hi, I recently started using the Twenty Thirteen theme and when I use Youtube's embed code for videos, the videos show fine when I look at the site from my desktop. The problem is when I view the blog from my mobile phone; there's a blank space where the videos should be.
I couldn't find this topic on this forum, so I'm not sure if this is a known issue. Am I not supposed to be using Youtube's embed code when I want to add a video to my post? Is there something I'm doing wrong?
