The All 4 App should offer live channels on it (unless a new software update has broken something).
I am assuming you can't see the live channels option anywhere under the App or when opening up the live channel it says something like stream unavailable due to rights?
I haven't got access to check my NOW box at the moment.
Though this issue has been reported in the past (see linked thread below).
Thanks, no nothing comes up when I open the pap apart from the list of categories etc in the left hand side. Can't see an option for live TV either.
Maybe it's an old version of the app and deleting and re-installing would work?
