It’s about to publish
Ocoya locks a post two minutes before its scheduled time. Once inside that window the caption, media and schedule are all fixed. That’s the same two minutes you can’t schedule inside — Ocoya needs the lead time to queue the post, and letting you edit while it’s being handed over would mean publishing something different from what you saw. If you need to stop it, you have those two minutes to delete the post. After that it’s going out.It’s already published
A published post can’t be edited from Ocoya, and it can’t be rescheduled:Posted posts cannot be rescheduledWhat’s on the network is now an ordinary post on your account. Edit or delete it there — Ocoya doesn’t reach back into published content.
It’s still generating
A post Ocoya is writing shows as Generating and is locked until it finishes. Wait for it, then edit normally.It partly failed
A post at Needs attention published to some channels but not others, and can’t be rescheduled as a whole:Posts needing attention cannot be rescheduledRescheduling would publish it twice on the channels that already worked. Remove the channels that succeeded, then reschedule the rest. See Why didn’t my post publish?
Approvals are unavailable too
The same locks apply to sending a post for sign-off:Approval is unavailable while this post is lockedIf a post is publishing, published or generating, it can’t enter an approval flow. See Post approvals.
What you can always do
Duplicate it. A locked post can still be copied, and the copy is a normal editable post. That’s the way to reuse a published caption, or to salvage one you couldn’t stop in time. See Edit, duplicate or delete a post.Related
