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.

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.

Start by reproducing the order flow on Android 14, then trace what happens after the order API response when the customer app should navigate away from checkout. Check the post-order navigation and screen rendering path for the grey, non-interactive state. Done means a successful order reaches a confirmation or tracking view with order details and a success message.
