Hello Team,
1 - We are unable to create a sub-task or a child in the Initiative with the type Epic or Story,


2 - If an epic is created before the initiative, it is not possible to associate this epic with the created initiative. The solution would be to update the ParentID field of the epic, but this field is not available on the screen. But when we try to add it, we only locate "Parent Link" as shown below :
Can you please help us, with these 2 points?
Thank you in advance
