Good point. Perhaps they could implement a feature that indicates there has been a response submitted but not yet approved. Possibly it could include when it was sent, who the reply is from, whether the approver has seen it (and when they saw it). That would at least make it apparent when someone is withholding approvals for an unreasonable time.
Sometimes I grab my daughter's phone because she left it there, and the most recent imessage notification shows up as soon as it detects being picked up. Most commonly seen "most recent message" is "Bitch leavin me on read angry emoji..."
