Hi,

Symptomes:

-there is an employee has the privilige of editing the PRs outside the PR approvers.

-after submitting the PRs for approval,sometimes this employee needs to reassign and edit the PR and submit again for approval.

-but we noticed there is a change in approval hierarchy,it should be the same of original one.

-we have build the configuration rules of PR approval based on the requester username not preparer username according to this issue.

i don't know why there is a change in the approval path,kindly advise.
