In the lead-up to the release of Pokémon Scarlet and Violet next month, The Pokémon Company has announced it will end support for specific online services in the previous generation of games Pokémon Sword and Shield.
As explained via Serebii.net, the "Wild Area news" is set to receive a final update on 1st November, which will add Pokémon not regularly available like Gigantamax Snorlax.
Battle Stadium's ranked season will also no longer be updated after 1st November, and these results will no longer be featured in the mobile and Switch application Pokémon HOME. Online competitions will conclude as well.
Friendly competitions will still be available, but won't display in Home from December 1st, and Y-Comm features and "other online features" will apparently still be accessible. If we hear any other updates about this, we'll let you know.
