First, queue for a random normal dungeon pug. Three players accept the ready check, one player doesn’t and you get stuck waiting for that player.
The issue is the player that didn’t accept the ready check yet doesn’t get timed out of the queue. Waited almost 10 minutes for the 4th person to accept the ready check and ended up having to leave the queue and restart. This has happened 4-5 times over the last couple of days.
