Better not have made plans for Pinsir Raid Day. That is because Niantic has recently cancelled Pinsir Raid Day. This Raid Day was originally planned to happen on Sunday, June 28th as part of the Bug Out Event.
There is no word on why this event was cancelled. Perhaps it was cancelled due to rising numbers in COVID-19 cases throughout the United States and world. Though, this is all speculation.
