If you see an error message saying "we're working hard on your list at the moment and can't let you perform this action at this time" while trying to connect a CRM List to an Email Marketing list, chances are likely that there's a pending job stopping the CRM from being able to connect to Email Marketing.
This error happens when there are incomplete tasks that the CRM is trying to accomplish behind-the-scenes.
The solution? Clearing those out to free up the CRM to associate your CRM list.
