Sometimes a site you would like your kids to access may be blocked by a filter category. Instead of disabling the whole filter category, you can simply add the site under Custom Filters as "Allowed".
1. Select the user profile from the homepage
2. Select "Filters" from the user's profile.
3. Select "Manage Custom Filters" from the filters list.
4. Enter the website address of the site you wish the user to access, select "Allowed" from the toggle and tap on the "Add" button. You will see the name of the site appear on the site list below.
