Niantic is planning to release a special Timed Research questline for those affected by a Pokémon Go Fest 2024: Global issue that happened over the first day of the festivities.
During day one of Pokémon Go Fest 2024: Global, Special Backgrounds, which are a special postcard art background that can appear behind certain Pokémon in raids, were not obtainable when using Remote Raid Passes. To compensate for the issue, Niantic plans to give trainers guaranteed Special Background encounters sometime soon.
