Riders are not receiving orders within their designated zones.

Summary:
I created a specific zone, registered a rider within that zone. However, when I places an order, the rider is not receiving any orders, even though they are both located in the same zone. This process is not functioning seamlessly as expected.

Expected Behavior:
The riders should receive an order when a user places an order.

Current Behavior:
Riders should be receiving orders within their designated zones.

How it occur:
I established a zone, subsequently adding a rider, and then assigned that specific zone to the rider.
Orders are being received within the restaurant app but are not appearing in the rider app.

The issue names no files or tests. Start by tracing the flow from zone and rider assignment through restaurant order receipt to rider-app delivery, then reproduce the described setup. Done means an order placed in a rider’s designated zone appears in the rider app as well as the restaurant app.
