Pokémon HOME is a new app that enables Trainers to continue their Pokémon adventures beyond a single game system and manage their collection of Pokémon across many of their games. Pokémon HOME is available now on Nintendo Switch, iPhone and iPad (App Store), and Android (Google Play) devices.
Pokémon HOME is undergoing maintenance in order to resolve the Hyper Training information issue. To have your Hyper Training information restored, you will need to move any Pokémon you transferred from Pokémon Sword and Shield back to Pokémon HOME before maintenance begins.
The maintenance period will last from 01:30 to 11:30 UTC on February 25, 2020. After the maintenance period ends, you will be able to transfer your Pokémon from Pokémon HOME back to Pokémon Sword and Shield with their Hyper Training information restored.
