Approval delegation is not working when Application role is used in approvals

Summary:

Hi All,

(We have defined a category for requisition and offer approval tasks in bpm.)

Recruiting approval delegation is working fine where Management Hierarchy is used in approval setting for ex. if hiring manager is the approver and if delegation is on for them then it is delegating.

But when Application role is there in approval and user A has that role and is delegating to user P, still it is not getting delegated to user P. It stays with the application role and user A can see the approval notification.

We want the approval to go to user P if the approval comes to user A even with Application role.
