I have some issues to ask about approve;
1. Approved request can be changed by users. It's not right cause a user can change the numbers or content after the approve. Is there anything to deny that?
2. It's a rare issue but we saw that 2 or 3 times. Sometimes Approver does not seem on Approvals tab as you can see on the first image. You have to remove and reassign to approver then.
3. For example, 3 person shown in stage. 1 person approved the request. other 2 person still shows the request in my approvals and take invalid key failure as you can see on the second image
