Switch version 6.1.0 comes with update for the Joy-Con controllers
When Nintendo issues a new firmware update, it sometimes comes with a related controller update. That has happened once again with version 6.1.0.
With the latest Switch upgrade, you’ll find a Joy-Con controller update waiting for you. Access it by visiting the system settings, going to the “Controllers and Sensors” tab, and then selecting “Update Controllers”. We’re never quite sure what’s involved with these controller updates, but there’s certainly no harm in going through with the process.
Thanks to Cameron for the tip.
