Hi Adrian,
The best bet is to go to the job page on the current project you're trying to send a notice on. There's a documents tab on that job page- see if you have a doc there and what status it is. If not, you can always create new document from your job page and make sure it is being sent to the parties you select.
Support is available via live chat in your account and at 866-720-5436. I hope this helps! Happy Friday!
