This is something new, at least to me. I've been working through several of the Mobile Ed Courses and since the latest update to L6, whenever I click to start the next video segment, it opens a NEW tab instead of using the already open tab with the previous video that I just watched.
If I just select the next video by using the arrows in the current video tab, then all is well. However, if I use the arrows in the currently selected tab, then the transcript of the video isn't available in the other tab. It doesn't seem like that big of a deal, but it is annoying to have to "close" one tab with a video already in it.
