I have. an LG43UQ91006LA.I am having problems with the ITVX app, it keeps buffering as much as 5 times over a 1 hour programme after the buffering I get a banner come up telling me I have a problem with my internet, but everything else is working the banner disappears after a few seconds and everything works until the next buffering, just wondering if anybody else has the same problem? I have no problems with other apps, BBC I player,Channel4, My5. If I use Amazon Firestick all the channels run smoothly including ITVX.
