Hangouts for IOS Improves Notification Support, Adds Quick Responses
iOS: Google updated the Hangouts app today with a few useful features that finally add proper support for iOS 9.
Big update here – adding quick replies to notifications. You can now reply directly from the notification itself or from the Action Center. Otherwise, this update does several things to improve notifications from all angles, including adding group names and including contact names in Google Voice notifications.
