I have a new iPhone XR running iOS 12.1.
When I get a new notification (such as an iMessage, a Reminder, etc.) on the lock screen, I should be able to long-press on the notification (instead of force/3D touch) and see shortcut options (or quick reply, in the case of iMessage).
These options are all enabled in Settings and I have tried rebooting my device and it still doesn't work. FaceID has unlocked the device and I know additional options are available because I can still swipe notifications to the right and select "View" which shows what I would expect to see when long-pressing the notification.
I submitted a radar to Apple, so hopefully they address it. But I just wanted to see if anyone else has run into this and found a solution.

It isn't that it is malfunctioning, Apple has not added support for long press on lock screen notifications. They have on the iPad, so there is future hope.
