Fiori My Timesheet "Auto Approval" Issue

Hi Gents,

We have recently extended the Fiori My Timesheet App, and for some user Auto Approval is configured in backend for the time entry they do.

The issue is that the status of entry is remained "Sent for Approval", and not changing to "Approved". However, its been only 18 hrs since they booked the Timesheet.

Just wanted to know if any configuration needs to be done for this automatic status change from "Sent for Approval" to "Approved"?

(OR)

Does it take more time to change the status to "Approved"?

Appreciate your help?

Regards
