In eloomi we use a queue system to handle tasks like adding users to Departments, exporting reports and assigning courses to users. This is to ensure that you as an Admin can continue working on your tasks while the system processes these tasks from the background.
In some cases, when hundreds of users are assigned to a department, courses are assigned simultaneously and emails need to be sent out - you may not see this happening instantaneously. However, rest assured, that the system is processing these tasks through the queue and these tasks will be processed continuously until all are completed.
