A user was working on an email this morning and clicked through to Schedule it. In the scheduling process, she got an error message that said a server error caused the scheduling not to occur. So, she scheduled again and it went through. Scheduling tab showed one email scheduled at 8:30. The issue is that at 8:30, the email was distributed twice to the same audience. So, the original try to scheduled did work, but did not display as a scheduled message. Any insight?
