This guide will let you know how to Add Crossplay Friends in Apex Legends. You have to follow the step-by-step instructions in this guide to add friends to PS4, PS5, Xbox, and PC.
You will need to go to the option settings, scroll down and enable the “Cross Platform Play” option, as shown in the image below.
After that, you have to close the menu and tap on the Friends icon at the bottom right side of the screen.
In the Friends tab, you will need to press the triangle button from the controller to open up the find friend search bar. You have to type your friend’s username and press the triangle button to start the search.
You have to select the account and press the X button from your controller to send a friend request, as shown in the image below.
You can also see them on your friend’s list, and you can join or invite them by tapping on them. You will see an option “Crossplay invites” on the left side of the screen; if it is set to “deny all”, then you are not going to receive any notification of invites from your cross-play friends. So you have to set it to Display.
