Help with Fortnite problem?

I'm with a buddy. We installed Fortnite on its Ps4 for the very first time. Now I want to play with my Acc on his Ps4. I play on the pc. How do I now connect my Acc with the Ps4 without starting a new profile?

All you have to do is log into the PlayStation with the PS4 account that is linked to the Epic Games account.

You should then be able to play the game as usual (with the progress made).

/ Edit: If you don't have a PS4 link yet, use it for the current account, so you don't have to log in with a new account.

Create a PSN Acc, link your Epic Acc to the PSN Acc and register the PSN Acc on the PS4
