Which automation feature is not available when using a formula column as a due date?

The choice stating that automated reminders are not available when using a formula column as a due date is accurate. In Monday.com, when you use a formula column, it can perform calculations and generate outputs based on the data in other columns. However, formula columns are static in the sense that they do not trigger automation features directly, including automated reminders.

Automated reminders typically require a date column that can be recognized as a trigger for actions like sending notifications or alerts. Since formula columns do not hold a static date value that can be used for these automations, features like setting automated reminders become unavailable.

In contrast, notifications based on dates can function with actual date columns, and integrations with external tools can often work even with formula columns as long as they reference other column data. The creation of new boards from templates is unrelated to the specific capabilities of formula columns and does not depend on whether the date is derived from a formula or a standard date column.
