I have two older Samsung tvs which I can easily add apps to the Home Screen. My newest (Samsung 55 inch crystal uhd 4k) has no option to add YouTube to the Home Screen. I can only edit what is already there. If I press and hold it just opens the app. From the app screen there is no settings option in the upper right corner. Resetting the tv by holding the power button didn’t work either. Why is this so hard???
