Done" Button Not Visible When Default Address is Pre-selected During First-Time Checkout

Nobody has claimed this yet.

Describe the bug
When placing an order for the first time, the default address that is automatically selected on the checkout screen does not display a “Done” button, preventing the user from proceeding. The user has to manually select another address for the “Done” button to appear.

To Reproduce
Steps to reproduce the behavior:

Go to the app and add an item to the cart

Proceed to the checkout page

Observe that the default address is automatically selected

Notice that there is no “Done” button

Select any other address manually

Now the “Done” button appears

Expected behavior
The “Done” button should appear when the default address is selected, allowing the user to proceed without needing to reselect an address.

Smartphone (please complete the following information):

Device: iPhone 12

OS: iOS 17 (please update if different)

Additional context
The issue only occurs during the first order when the default address is pre-selected. Manually changing the address triggers the appearance of the “Done” button. This could confuse first-time users and hinder successful checkout.

Start by reproducing the first-time checkout flow on an iPhone or iOS simulator: add an item, proceed to checkout, and observe the pre-selected default address. Trace the checkout address-selection entry point and compare it with the manual-selection path. Done means the “Done” button appears and permits proceeding when the default address is already selected.
