Based on somebody else saying they had a problem with it, I tried to schedule my previous post instead of publishing it immediately; it published immediately anyway. I’d never tried this before but I assume the feature hasn’t been nonfunctional for the entire time that it’s existed, so it’s probably yet another example of an “upgrade” making something worse.
I’m scheduling this post for 6:00 PM Central Time tonight (Dec 10), so if you see it before that, this makes twice.
(Or maybe it was just a time zone issue? Can the first person who sees this please comment and say what time it was?)
