I have a UE40JU6445K comin up for 2 yrs old. I have the Now tv box on another set but I was delighted to find this app on my then new Samsung. But it is a mess in all the ways described by the other users. Basically it doesn't respond properly to the remote control. It needs an upgrade. In the meantime I' m finding that the long press on the Exit button straightens it out for the next use. All the other apps work perfectly.
