How to unschedule a post and move it back to drafts
Open the scheduled Buzz on the Calendar, press Unschedule, then Move to drafts.
It opens in the composer as a draft with its pictures and accounts, and nothing goes out until you schedule it again.
You can unschedule a Buzz until 2 minutes before it goes out.
Unschedule a Buzz
1. Open Calendar in the menu, or press l.
2. Press the scheduled Buzz to open it in the panel on the right.
3. Press Unschedule, then Move to drafts.
The Buzz opens in the composer as a draft, with its pictures and accounts, and it sits under Drafts in the sidebar on the Buzz page. It no longer shows on the Calendar, which only shows what's scheduled, waiting for approval or already out.
Note: A Buzz locks 2 minutes before it goes out. After that it can't be unscheduled.
Delete a scheduled Buzz
1. Unschedule it as above.
2. In the composer, open the … menu and choose Delete draft.
Schedule it again
Change what you need in the composer, press Schedule, pick a day and a time, and press Schedule Buzz. To only move it to another time, you don't need to unschedule it: see change a scheduled post.
Questions
Where are my drafts?
Under Drafts in the sidebar on the Buzz page. The Calendar doesn't show drafts.
Why do I have to unschedule a thread to edit it?
A thread, or a Buzz with its own text per platform, can't have its words changed while it's scheduled. Move it to drafts, edit it in the composer and schedule it again.
