Mail Undo Send button has disappeared
Working in Sonoma 14.5:
The "Undo Send" button in Mail has disappeared.
In the Mail Settings window I have tried to set it to 10, 20, or 30 seconds to no avail.
I have quit. I have quit and rebooted. Nothing brings it back.
I have done nothing recently, of which I am aware, that might cause this.
Suggestions?
