Issue Summary

Currently, Jira Automation rules allow accessing the displayed name and Account ID of the previous user of a User Picker field using respectively:

{{fieldChange.fromString}} 

 and

{{fieldChange.from}} 

However, there is no direct way to retrieve the email address of the previous user at the moment of change. Please enhance these smart values to include the capability of retrieving the email address from a User Picker field's previous value.

Workaround

A temporary solution involves creating an additional User Picker field to store the previous user value. When the primary User Picker field changes, the automation rule can update this secondary field with the previous user information. Emails can then be sent using this secondary field as the recipient. While this method achieves the desired outcome, it involves additional configuration and maintenance, which can be seen as excessive for such a straightforward task.
