After completing a level, I proceeded to complete required three quests. I have been limited to 2 options ONLY: Ask Friends or Purchase. What has happened to Option #3 (Play Quests with a 24 hour wait time)?? I prefer this method.
Hey Pat, in order to be able to play the mystery quests, you should disconnect 3G/4G and WiFi; they then should become available for you. I always get them by doing that.
