I am using Jira Software Cloud Free version.
I have a Classic Project and I am mainly using the New Issue View.
I tried to show the field Parent Link on sub-task.
However, it does not work.
I inspected the reason by using the Old View feature Where is my field?
I got the error is: The field 'Parent Link' does not have value for an issue and will not be displayed on the view.
But as shown in the photo, my current issue is a sub-task and it does have a parent.
