I purchased a new TV (LG 65UM7300PUA) last week that was just delivered on Saturday (12/14). I stream TV through the youtube TV app. It simply doesn't work properly and is not reliable. I've reached out to youtube TV and they do not see a problem on their end. The app works fine on other TV's/devices. But it does not work properly on this TV. Could this actually be a TV thing and not an app thing? I've un-installed/re-installed the app as well as reset the TV back to factory settings and the app still doesn't work. Do you have any suggestions? Would it be best for me to just exchange the TV? And how do I do that?
