Hi Experts,

As per the approval configuration for resignation, When employee submits resignation it would go for immediate line manger approval and it is working fine. But Line manager couldn't see any details of resignation in Approval Notification except the Approve, Reject, Action Buttons as like the below.

Manager could able to approve and reject but couldn't see the resignation details in notification.

Do any one have any idea what is the reason of the issue. Also I observed that this is issue is only for few managers and for others details are showing normally.
