PS4 split screen issue

Not sure which version first off. Secondly, the issue i'm having is i cannot do split screen on the PS4 due to the 2nd controller popping up with 'sign in to PSN account' i've youtubed it and even looked on Mojang's tech pages and they all say to make sure the world is turned off to multiplayer and It is. However, i still cannot turn on a split screen. Any help or work arounds would be greatly appreciated.
