I’ve setup up purchase order appovals with email notifications, but I’m only able to send the notification to the purchase order owner using ((Document.OwnerID.EMail));. I’m trying to use ((Approval.ApprovedByID.EMail)); to send the notification to the approver, but the ((Approval.ApprovedByID.EMail)) value is returning an empty string.

What is the correct value to use to send the notification to the assigned approver for the purchase order. I’m not using approval workgroups, just a single defined approver. This is on version 2024 R2.
