The mini player is available cross-device, including Xbox and Apple TV and allows you to keep watching a video whilst browsing other sections of the app. The mini player is displayed in the bottom right-hand corner of the screen you're browsing and will remain consistant as you browse different screens.
The mini player launches automatically when you navigate away from a video and can be closed using the cross in the top right-hand corner. To pull up the player, simply tap on the left-hand side of the mini player (where the video is playing). You can also skip to the next or go back to the previous video using the player controls that are displayed on the right-hand side
