A new Special Research quest believed to involve the Team Rocket GO leaders, “A Challenging Development,” has appeared in Pokemon GO.
As Niantic’s Support website says, you can complete the Special Research quests involving the Team GO Rocket Leaders and Giovanni once a month. However, you need to have completed the Special Research quest for last month, “Looming in the Shadows,” in order to complete this Special Research quest. You also need to complete the “A Troubling Situation” quest in order to complete “Looming in the Shadows.”
Here’s what the support website says on the matter:
Trainers can receive Giovanni Special Research once per calendar month. For example, if you complete your September Giovanni Special Research in mid-October, you’ll receive new Special Research shortly after. If you complete the September Research in mid-September, you’ll need to wait until midnight on October 1st (local time) to receive the Research again.
