How can you spy in fortnite with ps4 AND xbox?

I wanted to play fortnite with a friend today. She has an Xbox and I have a PlayStation 4 but we did not get our friend requests. Is that even possible to play with ps4 and xbox?

Yes it works. Try again. Vllt times should send the other person the friend request, went with me even after a few painting only.

In your game, go to the epick account and add friends after that accept the request and invite them to a lobby have fun both of you 😊

Thanks for the answer. We have tried several times but somehow it is still not XD

Of course she has to adden you before that is important too, as she enters your epick name
