There isn't too much new here
The latest Nintendo Switch firmware update, version 14.1.0, has just dropped, though it doesn’t add much. Here are all the patch notes:
“Platinum Point Notification Settings” has been added under Notifications in System Settings.
Unclaimed Platinum Points earned from completing Nintendo Switch Online missions on your Nintendo Switch system will generate notifications. Nintendo Switch Online missions and rewards are not available in some countries and regions. For more information, see How to Complete a My Nintendo Mission. Setting these notifications to OFF will hide the notification sent when there are unclaimed Platinum Points.
As someone who’s forgotten to claim Platinum Points and has noticed when it’s too late before, this feature, albeit small, is much appreciated. You can download the update yourself right now on your Nintendo Switch.
