Hi, my LG webOS TV TN520S is running software version 05.45.45 and since then the channel 4 and channel 5 apps are broken. You can start to watch a program but as soon as the first set of adverts start, the app just loops and you cant progress past the adverts. I a wondering if this is because the TV is running the latest version of its software (I've searched for newer versions but none are shown). Has anyone else had this problem and is it possible to install a previous version of the TV's software to see if this resolves the problem.
