Login fails on Android unless using "demo customer" email

Describe the bug
When attempting to log in through email on Android, users are unable to log in unless they use the "demo customer" email. Any other email address results in an error message.

To Reproduce
Steps to reproduce the behavior:

Open the app on a Samsung Galaxy A15 (Android)

Go to the login screen

Enter any email address other than "demo customer"

Attempt to log in

See error message

Expected behavior
The login should accept any valid user email, not just the "demo customer" email.

Screenshots
If applicable, add a screenshot of the error message displayed.

Additional context
This issue seems to be specific to Android. The login works fine on iOS (e.g., iPhone 13 Pro Max). The problem could be related to platform-specific login handling or authentication checks.

Start at the React Native login flow and reproduce the failure on a Samsung Galaxy A15 using an email other than the "demo customer" address. Compare the Android behavior with the working iOS flow and identify the authentication check involved; done means valid user emails can log in on Android without changing the existing iOS behavior.
