I’ve tried with 2 people to get this achievement but it’s simply not unlocking. They both have the achievement. We tried that I joined to them and they joined to me, did duels and missions. I even reinstalled the game. I have no idea why it’s not unlocking.
Same here i need it and it wont unlock
Well, I’ve tried with a third person and the achievement is unlocked. It’s still unclear to me why it didn’t unlocked before
