UNUserNotificationCenterDelegate not firing for remote notifications

Notification center delegate is firing for local notifications but not remote, when using UNTextInputNotificationAction on a WKUserNotificationInterfaceController.

 func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)

I get a response when the user enters text and submits, but only for a local notification. For the remote notification - the delegate method never fires. The notification delegate is a singleton that's assigned in the watch's ExtensionDelegate's applicationDidFinishLaunching method.
