Login Button Shows Error on First Click When Using Email in iOS Customer App

Describe the bug
In the iOS customer app, when a user tries to log in using their email address, clicking the login button for the first time triggers an error message—even when the entered credentials are correct. On the second attempt (with the same details), the login proceeds successfully.

To Reproduce
Steps to reproduce the behavior:

Open the iOS customer app

Navigate to the login screen

Enter valid email and password

Tap the login button

Observe an error message

Tap the login button again without changing anything

Login succeeds

Expected behavior
The login should work on the first attempt if the entered credentials are correct. An error should only appear if there’s a genuine authentication issue.

Additional context
This issue could be related to a delayed input binding, form validation bug, or premature API call before the input fields are fully registered. It may also be affecting first-time session initialization or token handling.

No source files, tests, device details, OS version, or app version are named. Start by reproducing the first-click failure in the iOS customer app with valid email credentials, then trace the login form submission and authentication request; done means a valid login succeeds on the first tap and genuine authentication errors still appear.
