It's about time. I've got a firestick that has been unused for a year, because i don't have enough plug sockets to plug it in. My extension thingy has 6 sockets. I have plugged in my tv, xbox, playstation, desktop pc, monitor and now tv box. i already have to unplug something to use my printer.
These tv streaming companies need to realise that sockets (and hdmi slots) are at a premium. Plus the electricity usage of all these boxes and sticks is terrible for energy conservation. Also all these unnecessary devices, remotes and cables lying around everywhere.
What Amazon Fire device do you have and are you a UK NowTV customer and not based in the Republic of Ireland.
Also if you are using a VPN make sure it is set to UK or switched off.
When you say Prime TV i am assuming you are accessing the NowTV App with your NowTV account login details and not by any other means.
