Hello. I bought a smart Samsung TV and I also bought a wireless mouse, which only wanted in applications, i.e. I can move normally in the browser, but not in you tube anymore. Also, after enabling the button responsible for the selection of the application, I can not move. I checked the same mouse on another LG TV there, it behaves completely differently after switching on the TV, I can control it immediately, the cursor on the screen is visible, I can also change channels with the "wheel". I have a question whether my TV does not support my expectations, or if another type of mouse would change something. I will also add that in the TV settings there is an option to connect the mouse and keyboard via bluteoth. The question is, does it make sense to buy such a mouse?
