I have scheduled a post for tomorrow, but would now like to have it go back to being "unscheduled" so that, in the future, I can simply press "Publish" and it goes live immediately (as normal).
However I can't find any way in the user interface to do this? I can edit the scheduled post date, but there is no way to simply unset it? This seems a bit restrictive? Is there a function/hook I can run to clear the scheduled post date and have it revert to "immediately"?
