iExpense AP Approval notifications

Hello,

Regarding the AP Approval requirement after the employee's manager approval, I have two questions:

1. The auditor currently set up in the system are not receiving any sort of notifications indicating that an expense report is assigned to them and waiting for their approval.

managers receive such an email saying they have an expense report waiting, but not the AP Approval auditors.

2. Who is supposed to receive the email notification for fall-back auditor? When we have expense reports assigned to this auditor how can we be reminded?

We just implemented iExpense and are going through our first few audits so have not figured it out yet.
