Thank you very much for your continued support of Pokémon HOME.
Pokémon registration status being reset for game-specific Pokédexes
Using the Wonder Box's "Receive all Pokémon" function between May 18, 2022, at 01:00 UTC and May 26, 2022, at 14:00 UTC may have caused some Pokémon to become unregistered from individual games' Pokédexes.
This issue was resolved via a server update on May 26, 2022, at 14:00 UTC.
Pokédexes will properly register Pokémon received in Pokémon HOME after that time.
We hope you continue to enjoy Pokémon HOME!
