I can't see a way to get a user notified of a status change on their request via the In-app route. Just by emails. e.g. A user sends a request which is either approved or rejected. They'll receive an email (if they have those turned on) or they can view this via the home screen or their request queue.
I think that's normal (from memory). In-app notifications do not mirror email notifications exactly, and I think in the past I haven't seen a lot of status change notifications in the in-app space.
