Weekly Challenges will be available in Pokémon GO at the start of the new season titled Tales of Transformation. Weekly Challenges is a new way to connect with other Trainers and earn rewards.
What are the Weekly Challenges?
At this time, we do not know what the Weekly Challenges are. However, it is a social feature that allows a Trainer to team up with up to three other Trainers to take on a group challenge each week. There will be different challenges with varying degrees of difficulty every week. Some of these challenges can be completed alone. However, to complete the challenge before it expires and be able to get the rewards, you will need the help of other Trainers.
Completing the challenges will grant the group of Trainers different rewards and XP while growing their Friendship level.
How to Start the Challenges
You can start a group with Trainers on your Friend List. Your group is not limited to Trainers you can physically meet. You can start a group with any of the Trainers on your Friend list, no matter where they are. You can also be matched with a Friend on your Friendlist who started the group. In addition, you may be matched with other Trainers from around the world as a new way to discover friends. You will be able to see all these on a new tab next to your profile page!
