I have been having problems with my 4OD app suddenly, with no obvious reason. I can search and move around looking for programmes, but when I click play, I get the Channel 4 adverts, but then it will not play the programme. the message I get isALL4-011: This content is currently unavailable. Please try again later. I have tried a number of different shows and the same things happens no matter which programme I try. The on demand service works on my computer, so there seems to be something wrong with it playing on my TV. I have reset the smart hub (after seeing some similar old posts), searched for software updates (apparently there aren't any), and I do t know what else I can do.
I'd appreciate any advice on how to get this working.
My TV is UE43NU7120 and has software version T-KTSUDEUC-1310.4
