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.

Reproduce the described flow by creating a zone, assigning it to a rider, and placing an order. Trace the order path from the restaurant app to the rider app, checking where zone assignment is applied; done means the rider receives orders placed within the rider's designated zone.
