Hi, I'd like to work on this issue.

I've reviewed the thread and confirmed there is no active PR for it.

Planned approach: The issue likely stems from the login flow not properly persisting or retrieving the user's email after OTP verification; we will inspect LoginActivity.java and OTPActivity.java to ensure the email is correctly passed and stored (e.g., in SharedPreferences or Intent extras) and validate that the login API call uses the verified email instead of a stale or null value.

I'll submit a focused PR once the fix is ready and locally verified.
