I've tried multiple times to install the Now Tv app on the firestick and Fire tv cube but as soon as you install, it displays a not installed message. I've looked everywhere i can think of to find a solution to this to no avail. Every tutorial i've come across says nothing of this problem. Anyone else here know why this is? Or is it just Sky...yet again with their massively over the top security not allowing any of their software being installed on any other device other than one they have commissioned!!!
