The Pokémon Sleep bug affecting the Snapshot Surprise feature has been fixed, restoring normal gameplay for all users. Players can now take snapshots and receive their rewards as intended without errors or interruptions. The update ensures that the feature works smoothly, letting trainers fully enjoy the daily surprises and interactions in the app. If you experienced issues with Snapshot Surprise previously, everything should be back to normal, so it’s a good time to jump back in and make the most of the feature.
