I've got a bunch of announcements in a course I imported that were delayed in their original course. Now that I've imported them into the new course, the Delay date is unset. I go Edit the Announcement, check the box to Delay Posting, and enter a valid date a few days in the future. When I click Save, the spinner appears briefly, but then nothing happens. I remain on the Edit page. The post isn't saved, and the Delayed Posting isn't enabled. The post remains active.
Is this a bug, or am I missing something related to Delaying the posting of an active anouncement?
