Soldato
I occasionally use the link feature when I want to send something I'm talking about, to the TV. But it can be very annoying to then unlink for "normal" use again. It used to entirely close the YT app on the TV.YouTube just randomly decided to link the app on my TV and phone. A feature that is monumentally annoying.
Sometimes I look at comments on one video on my phone while playing another video. Not possible if your devices are linked as your TV starts whatever you open on your phone.
Switched straight off.
