When I play NRFTW on GFN, often the game will boot to a black screen with the audio still playing. There’s nothing to interact with so my only option is the close the stream and reconnect to a new one.
I don’t know if it’s actually the game failing to launch properly or if it’s something on GFN’s end like there being a window I can’t interact with in front of the game. Guess you’d need to liase with them.
Mayhaps it could be the platform/hardware if using it on something different.
I Haven’t seen any complaints otherwise about Samsung TV apps or such, and I know/think Shield TV hasn’t gotten NRFTW activated yet on it, unless they already got that fixed as initially it wasn’t opted in for some reason on the app/tv apps
