Tasks can be created as recurring – handy for regular to-dos such as monthly billing. You find the option when creating a task.
How to do it
Open the tasks area via the bell icon and click Create task → From scratch. Fill in Title, Due date and, if needed, further fields (incl. Team, lead time, estimated time, description). Enable the Repeat option at the bottom to set the recurrence interval, and save with Save and close.
The basics of creating a task are shown in Adding a task; creating from templates is described in Creating tasks from templates.
