Autoprovisioning roles not working for new hires

Summary:

Hello everyone,

We are experiencing issues with the auto-provisioning of roles; new hires are not receiving their roles.

We have the same configurations in both test and production environments, and it works in test!

We have correctly set the required LDG and HR Assignment status as Active + System Person Type as Employee.

The process "Autoprovision Roles for All Users" correct the issue when it runs.

However, we would like to understand what might be causing the issue.

Are there automatic triggering parameters in production? What should we check to ensure that automatic role assignment works correctly? without focus on the process. Why it doesn't working without it ?
