When you create an Auto Task template, you can choose when the task begins ("Schedule for") and set a time frame for the completion of the task ("Can start from" and "Must finish before").
These tasks are linked to the schedule of the reservation, and changes in the reservation's schedule may cause changes in the tasks' status. For example, if you change a reservation's check-out time, tasks with a "Confirmed" status linked to that reservation schedule revert to a "Pending" status.
This behavior is by design and helps ensure that the assignee of a task is aware of the change in the schedule. The task is reconfirmed when the assignee accepts the task via the Guesty mobile app.
Note:
When a reservation is altered, the relevant Auto Task will only update if the reservation status is "Canceled", "Pending", or "Confirmed".
