For our app if the user initially accepts receiving push notifications and then they indicate at some future time they no longer wish to receive push notifications: Will APNS return an error code on the next push notification indicating the user no longer wishes to receive push notifications for this app. If so, do we need to take action to stop sending push notifications? Can we always register a user for push notifications regardless of whether they indicate they wish to receive push notifications and just count on the device to filter what the user has not consented to receive or has removed consent. Thank you Bryan
