Clarification in ARW functionality for below two issues observed

Hi Team,

Our client uses ARW functionality, however they were facing below mentioned issues:

1. The first occurs when approver is reassigned after an account has been submitted for approval.  The account becomes locked and can no longer be approved. Can you brief me here how reassignment works in Account reconciliation workbench and what are the restrictions involved and also confirm whether this is fixed in PUM33 image.

2. The second occurs when a user has many accounts to submit for approval (Reconcilers and Reviewers) or mark as approved (Approvers).  If they use the select all, and some accounts in the range selected have already been auto approved, the action (such as approve) they try will not work.  The work around is to pick smaller ranges to approve, or approve accounts individually.  Some people have many accounts and this is burdensome.  On some occasions this issue has caused accounts to get stuck, and can no longer be updated.
