When you have finished watching a show within one of the players, you can get back to the Freeview App by tapping the Freeview link on the top left hand corner.
If this link is not visible, simply tap the screen and it will appear. If you have continued to browse within the player, this link back to the Freeview App will disappear.
When this happens, you can navigate back by utilising the multi-tasking feature on IOS devices. You can do this by double tapping the home button on the bottom of your device.
