Instead of adding repeated tasks manually, save time and use the Recurring tasks functionality. Each task is then automatically added to the task list of the doer (you or any of your team members) on the early morning hours of the day (not the deadline) of the task. For example, when adding a recurring task that you need to take care of on Monday each week, each task is created during the night before.
In order to create a recurring task, go to Tasks > Recurring tasks and click on+ New.
The displayed window is similar to the one used for adding a regular task.
Choose the interval and end date. The task can also be indefinite.
Select who is responsible for the task and who will this task be assigned to.
The list of recurring tasks can be sorted using regular filters (e.g. filter by projects).
You can also assign a task to another user, link it with a project, etc. by just checking the task or several that you'd like to modify.
By default, all new recurring tasks are ticked as active. If you wish to change the status of the task (not use this task for a while), click on the priority icon of the task (modify view will open up) and remove the tick from the Active checkbox.
To modify or delete a recurring task, open the task modify view and make your choice.
