A schedule can be active or paused. Only active schedules publish posts.
How to toggle
On the Schedules list page, use the toggle switch next to the schedule name. The change takes effect immediately.
Alternatively, open the schedule and uncheck the Active checkbox, then save.
Pausing vs. deleting
Pausing a schedule is non-destructive — your timeslots, channels, and posts are all preserved. Use pause when you want to stop publishing temporarily (holiday periods, content reviews, etc.) and resume later. Delete the schedule only if you no longer need it at all.
