how to stop "undo send" in mail
I have noticed big delays in mail leaving my iPhone and have occasionally shut down Mail on my Mac before the mail went out, only to notice the yet to be sent mail sitting in the Outbox more than 12 hours later. This was not happening before this new "Undo Send" feature, which I do not even need.
How do I turn off "Undo Send"? I would like to go back to the way things were before this feature was added.
Is there a way to get rid of "Undo Send"?
