What is the best way to set up crossplay over the internet? If you're using the Xbox app, go to settings first. To change your privacy settings, go to Manage Privacy Settings Log in at account.xbox.com/en-us/settings if you're using the web. Select your child's profile from the drop-down menu. Select Xbox One/Windows 10 Online Safety from the drop-down menu. Make sure that the first box, which deals with crossplay, is set to allow.
