The Parental Controls app for the Nintendo Switch gives parents the ability to oversee their kids gaming activity on the device. But sometimes the global age restriction setting that you are comfortable using for your child may disallow a game that you are comfortable with them playing. The app gives you the ability to whitelist games that are allowed even though the age restriction might fall outside your other settings. Lory Gil at iMore.com has a page explaining in detail how to add or remove games from your whitelist for the Nintendo Switch system. These features are often developed through input from consumers, so take the time to voice your concerns or desires to the companies you support through your purchases.
