How the reminder notification for the expiration of a task is triggered

Summary:

Content (please ensure you mask any confidential information):

Hi everyone

we are configuring the trips with the respective tasks.

Specifically, we are configuring the notifications and reminder notifications that the employee should receive.

We noticed that by setting the task expiration as in the screenshot below, the task "performer" does not receive any warning notification for the task expiration.

By configuring it as an attached screenshot, we expected that the day before the task deadline the performer would receive a warning notification.

Could you help us or provide some more information about it

Many thanks for your time,

Regards,
