I really don't know why but you will see they put $ 3.99 us dollar amount for this app but its can't be purchased as the Paypal link is a dead end. I know it works with the Shield and it connects to any server so long as your donation is active. I found one app, 'Stalker IPTV Emulator' which is easy to download and install but it is a trial version which lasts for 3 days and then you either have to sign up for one of their packages or it stops working. There are so many Stb emulators and so many different versions, you have to try them all and even then I found they either don't work or they weren't intended to be used with the Nvidia Shield Tv box.
