SAP SuccessFactors Recruiting Management
This is because Mobile Apply is enabled in Admin Center -> Manage Recruiting Sites. Currently, rules on candidate facing job applications cannot be used when Mobile Apply is enabled.
Rules will still work for Recruiters working on applications in the system, but not for candidates on the external career site. If Mobile Apply is disabled, the job application rules will work as expected for candidates.
Product Management is working on having job application rules work with Mobile Apply.
