All versions of Pokémon HOME will undergo a five-hour period of maintenance on Wednesday, June 17 in preparation for The Isle of Armor DLC.
The scheduled maintenance window is from 5 AM EDT to 10 AM EDT. During this time, “all functions” of Pokémon HOME will be unavailable.
“After this maintenance, users will need to update the Nintendo Switch version of Pokémon HOME to version 1.1.0, and the mobile device version of Pokémon HOME must be updated to version 1.2.0.”
Specific changes were not noted; however, the updated versions of the software will likely add new Pokémon coming to Sword and Shield via The Isle of Armor Expansion Pass.
On June 2, the Galar region’s partner Pokémon—Grookey, Scorbunny, and Sobble—became available in Pokémon HOME as Mystery Gifts; each of the three Starters also had their signature Hidden Ability.
We’ll be sure to update our Pokémon HOME Updates and Patch Notes web page with the full details once we learn them.
