Super Smash Bros. Ultimate has been updated to version 1.2.1.
The update wasn’t a big one and version 1.2.1 only contains various gameplay fixes according to the update notes.
As always in order to use online features, your software must be updated to the latest version. Local Wireless is not compatible between version 1.2.1 and earlier versions so you’ll need to make sure that all players are using the same version of the software.
Replays are compatible with Version 1.2.0.
