Today I have bought an wireless USB-HID Keyboard and connected to the TV (42PFL7606) which was correctly detected and after some testing the keyboard layout is also ok.
However I thought I could use this keyboard in the YouTube app, so I would not have to use the On Screen Keyboard.
It seems there is no integration with the keyboard is this correct, or I'm I missing a setting?
For me this was the reason why I bought the keyboard.
Thanks for the support
