Mark attendance based on 'Employee Checkin' for Employees

Hello everyone, I have created shift types and enabled “Mark attendance based on ‘Employee Checkin’ for Employees” but the auto attendance is not being created, I am not sure if I have done anything wrong in the configuration, appreciate any help please.

Shift Type:


Employee Check-In:


Thank you.


To mark auto attendance, ‘The Last Sync of Check-in’ should have a value, as attendance is marked based on that.
