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.

Start by tracing the order-placement flow from the restaurant app to the rider app, focusing on zone assignment and rider order delivery. Reproduce the reported setup with a rider and order in the same zone, then verify that the order appears in the rider app as expected.
