I have the same problem - great internet connection and all other Apps are fine. But All 4 nearly always hangs up on the "paid for by advertising" screen when I try to use it.
Resetting the TV does work at first - but the problem soon comes back a few days later. And the firmware says no updates required - all up to date.
So so what can we do Samsung?
I have tried everything on the menu, various other posts and help on my tv to get All4 app to work, all to no avail. It works on my iPad and Amazon firetv stick on my kitchen tv. So why can’t it work on my UE48HU7500T Samsung TV. PLEASE HELP.
i am not impressed by the apps that come with it apart from the tv and video apps. Amazon and Netflix apps are fine. The Browser is utter rubbish as far as I can see! Can anyone tell me what use it is? If I can get All4 working again I’ll be happy!
