My settings are all correct: Location, Region and Language and time and date!
YouTube was working correctly up to two weeks ago, then it changed.
Logging in to YouTube on Android phone with the same credential, does not give the same problem.
I'm not sure if this might be the problem, but I'm sure its relevant, after a recent LG TV update, whenever the TV reboots, it gives a message that the YouTube app certificates are outdated.
I then noticed that the TV does not update the date and time automatically, even though its set to Set Automatically.
If it was a Google problem, then the Android YouTube app would also display the wrong characters.
Please rectify ASAP - it's very annoying!
