Hello, Ive recently purchased a UE65SK8000 TV and on other TVs I've owned apps like Disney Life, BT Sport and YouTube have had the cast to button in the top right and pressing it cast that content to the TV while letting me use my phone (e.g. browse the web) without that interrupting or being cast.   Since switching to this TV the cast buttons are greyed out (on Samsung S8) and the only way I can cast to TV is by using the screen mirror function which is far worse quality than casting.   Anyone have any ideas why this is happening or how to resolve? The tv has YouTube and Disney apps installed on it but sometimes it's easier to find on phone.  Software on phone and tv is all up to date.    Many thanks    Chris ... View more
