Always waiting for the opponent

I tried to play in PVP when I chose the both invite friend and find opponents, it s always waiting for opponent and for a while it s just auto back to town page. Do we have to set anything before fight in PVP?

Thank you for anyone who helps.

If you’re in an unpopular league, it will be hard to find an opponent. If the PvP matcher can’t find anyone for you to battle with, it will kick you out of the queue and return you to town.

I don’t know about invite, though.

invite only works if the other person is also inviting you to battle.
