I'm wondering if anyone has had experience using picture-in-picture on an iPad or iPad mini? I was hoping that I would be able to watch a video while working in other apps. However, this doesn't seem possible. If I bring up a video on the web, then switch to another app, I lose the sound of the video. I'm not sure if the picture is there or not because I am totally blind. Does picture-in-picture only show the video and not the sound? If this is the case, it is very disappointing. I hope I am just doing something wrong. Any responses would be appreciated.
