Impossible to join a friend party

[Impossible to join a friend party]

Hello and sorry for my late answer, 

How can I set the game to public ? 

[Impossible to join a friend party]

Hello,

Since the last update, I can't join a party created by a friend. He creates the party and when I search for his party in the Lobby Multiplayer, I don't see his party so I can't join it.

Thank you, you make a very good job with this game.

Me.
