How does Adblocking work?
Adblocking will help you block web and video advertisements as well as requests to known ad servers. You can enable this for either a device, person profile or everyone. When you enable Ad-blocking for a person, this setting will be applied to all the devices assigned to that person.
When making changes to these settings, it may take up to 20 minutes for them to take effect due to cached settings. You can simply toggle your WiFi off and on if you would like to refresh your cache.
