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 reproducing the reported setup: create a zone, assign a rider to it, and place an order. Trace why the order appears in the restaurant app but not the rider app, then verify that a rider assigned to the order's zone receives it.
