[2022] I don't see my friends invit

Hello,
My friend and I just bought the game.
We've succed to invite each other for playing in ranked mode, but now it just doesn't work anymore.

When we send each others invitations , we can't saw any invitation.

We're really desappointed, how can we fix that ?

Thanks in advance


PS: He's on Epic games, I'm on Ubisoft PC
