In the meantime, a workaround is to type some Terminal commands if you're familiar with command line interface:

so annoying! it's such a useful feature

Yes it has been removed from System Settings and it’s a shame…

please contact Apple Support and send feedback to file a feature request for them to bring that feature back.

Yes, if you have executed correctly the command then the scheduling should be set. Nothing is "visible" in the graphical user interface of macOS.

The article states that the command

pmset -g sched

should list the configured schedules. Check if it lists the schedule you executed.
