The Pokémon GO Weekly Challenges feature is continuing its phased rollout and has now expanded to Taiwan and the United Kingdom. Players in these regions can start tackling weekly tasks for extra rewards, giving a steady rhythm of goals beyond daily and special events. The addition helps trainers build consistent progress and keep engagement high, while also testing the system in more regions before a full global release. With bonuses stacking up and new challenges each week, it’s a nice way to add structure to gameplay and make sure there’s always something to aim for on your adventures.
