When you are watching a show in a catch-up app (BBC iPlayer, ITVX, Channel 4, Channel 5, etc.), you can instantly exit the app and return to live TV with a simple long press on your remote.
Standard Exit: Pressing the Back key once will exit the catch-up app and take you to the Freely app homepage.
Quick Return to Live TV: To bypass the Freely app homepage and return directly to the last live Freely channel you were watching, press and hold the Back key on your remote control until the live channel plays.
