APEX EBS Login Returns APEX_PUBLIC_USER Instead of EBS User

Hello,

I am facing an issue with Oracle APEX EBS authentication in one of our applications.

• This happens only for one specific APEX application.
• Other applications using the same EBS authentication setup work as expected.
• all are the same [DB/workspace/package/procedure/app...everything]

Problem:
When logging in via EBS, the APEX session returns:

APP_USER = APEX_PUBLIC_USER

Expected Behavior:

• APEX should switch the session from APEX_PUBLIC_USER to the EBS user based on the URL parameters.
• Initialize_Context must execute on page load to set the correct EBS user session.

Debug output only shows:

samesite: none disabled (only allowed for secure cookies, with certain browsers excluded)
