Split Screen! For fortnite!!! HELP

I tride KevinPM03091 with KevinPM0309

Hi, this is what i found:

• First, make sure Player 2 is signed into a PSN or Xbox Live account. When you turn on a PS4 controller, it’ll make you choose a profile before you can do anything. On Xbox One, press the Xbox button and navigate to the tab where you can sign in.
• Once Player 2 is logged into their PSN or Xbox Live account, press and hold the X button on PS4 or the A button on Xbox One using the second controller to add them to the game in Fortnite. Player 2 can then log into their Epic account to get access to all
  their skins and emotes. It’s worth noting that only Player 1 needs to have Xbox Live Gold if you’re playing on Xbox One. PlayStation Plus isn’t required for Fortnite on PS4, so neither player needs to have a subscription to play Fortnite online.

The split screen doesn't work on my ps4 .

I can log in with 2 acounts but it doesn't work after a start the game !

i can't find splitscreen options, on deos ps4 have other version?
