Due to technical issues that occurred during the recent appearances of Uxie, Mesprit, and Azelf, a new event to make up for this will take place on Sunday, June 11th, 2023 from 11:00 a.m. to 5:00 p.m. local time in their respective regions in five-star raids. Those Trainers impacted by this issue will have all the Remote Raid Passes they used returned to their Item Bag plus one more.
