Repeat, in the task dialog, says when a task comes back: Weekly, on the days you tick, every so many weeks, or Monthly, on one day of the month or the last, every so many months.
- You owe one at a time: the next one appears when you close the one due now, so your list never fills with weeks of copies, and the Calendar still shows what is coming.
- A task collection is a run of tasks your team repeats, such as welcoming a new customer, made in Task templates. Apply it from a card's Tasks tab with Apply a task collection...: every line becomes a task on that record at once.
- Task templates can repeat too.
