Grey Screen Displayed After Placing an Order in Customer App

Describe the bug
After a user successfully places an order in the customer app, instead of being redirected to a confirmation screen or order tracking view, the app displays a blank grey screen. This gives the impression that the app has frozen or crashed, even though the order may have been placed.

To Reproduce
Steps to reproduce the behavior:

Add items to the cart

Proceed to checkout and complete the order

Observe the screen after placing the order

A grey, non-interactive screen appears

Expected behavior
The user should be redirected to a proper order confirmation page or order tracking screen with relevant order details and a success message.

Smartphone (please complete the following information):

Device: Samsung A15

OS: Android 14

App Version: [insert if known]

Additional context
This bug severely impacts the user experience by creating doubt about whether the order went through. It may be due to a broken route, missing screen rendering, or unhandled post-order API response.

No source files or tests are named. Reproduce the checkout flow on the reported Samsung A15 and Android 14 setup, then trace the customer app's post-order navigation and rendering entry points. Done means the order-completion flow shows a confirmation or tracking view with order details instead of a grey, non-interactive screen.
