I have no idea why Nintendo puts out patch notes for the firmware, but they don't include all the details. I understand some things just don't make sense to share with the public, but things like a Joy-Con update seem like a tidbit worth mentioning! You'll have to visit the Controllers and Sensors section of the Switch's settings to find the update controllers option, and then your Joy-Con update will kick off.
And this update does exactly what?
I hope it does something with the connectivity. I still get signal drift less than 5 feet away from the switch....
I didn't even know the joy-cons could be updated separately haha
The Update for the joycons allow you to turn on the switch with the home button, even if you accidentally hit another button
I hope that solves a issue that I had when playing ARMS on handheld mode. My left joycon stops being recognized in handheld mode and the games gets crazy because it thinks that I displugged the left joycon of the console.
