Hi there,
Thanks for writing in.
Surface is a touch device, a hybrid one. As of now, there are almost no boundaries between devices when it comes to hybrid (desktop - hybrid - mobile). A hybrid could be a desktop and could be a tablet. And since mobiles could also surpass desktop resolutions and other features, then it’s harder to detect which is which, hence, it’s safer to assume all touch devices are mobiles and tablets where some desktop features aren’t available, and videos will not play on any of touch devices. But, it’s on our list as a feature request, hybrid devices are bit complex since coding is only limited to the browser and not to the device where it runs.
Thanks!
