I am having an issue with the emails notifications being sent on a form I just created. I have shared the collaborator role with another person who is not receiving emails, and when I did some test submissions earlier, it took about a half hour before they were sent to my inbox?
This is the form in question: https://adobeformscentral.com/?f=GtfZo6QBXZ1WAp8BHN7xZg
The co-author or any person you have designated to receive email notifications needs to have an Adobe ID and have accepted (logged into) Formscentral invitation. From time to time out outgoing mail servers get backed up during high demand periods. If you continue to experience slow receipt deliveries please let us know the day and time you noticed the delay.
