More naughty words banned
The Switch firmware has been updated to Version 15.0.1, but this one is a bit different from the usual update. This is a “rebootless” update, which means you don’t actually have to restart the console once the update is applied. This update should download to your Switch automatically.
No official patch notes are shared for rebootless updates, but we do know that this firmware version has tweaked the banned words list. New banned words were added, and the list was tweaked in order to make sure inoffensive text isn’t accidentally blocked.
