Mate and I just tried it, you cant queue even though there is 2 people in the party. Confirm please.
I duo-queued recently. Might just want to try again?
You probably hit play again after a match and he accepted the invite too fast.
We both tried on different ends. I hit play and made an arranged game, then invited him. He did the same thing and nothing changed...
Okay for some reason it works sometimes, others it doesnt...
