Applying the "Respond to customer" transition to enter the "Waiting for customer" state for the "Service Request with Approvals" incident type does not cause the dialog box to appear to allow me to send an explanation to the client. The transition to the new state works correctly.
This also happens in a new incident type that I have created. I created a state and a transition both called Review. When transitioning to this state, no dialog box appears.
What configuration am I missing? Any help would be appreciated.
