We greatly appreciate all the feedback you’ve shared with us about the Raid Battle feature over the past few months. We’ve been carefully reviewing your feedback and will be making a few changes to the feature in response. These improvements will not require you to update your app, but they will impact your gameplay. Below are a few notes detailing the changes as well as a few comments from our development team:
- EX Raid Battle changes
- EX Raid Battles will take place most commonly at Gyms found in parks and sponsored locations.
- Trainers with a high-level Gym Badge are more likely to be invited to EX Raid Battles taking place at that Gym.
- Trainers who have completed a larger number of Raid Battles are more likely to be invited to EX Raid Battles.
- EX Raid Battle start times now take into account popular Raid Battle times at that Gym.
- Trainers invited to EX Raid Battles will receive an in-game notification if the EX Raid Battle is canceled.
- Trainers will receive Stardust and Premium Raid Passes when an EX Raid Battle is canceled.
