In the flow, I have restricted the flow action using access when (AssignedToMe) because the operator has access to functions such as transfer assignments, and access to change details in work cases w/o access to the assignment when not assigned. 

When the case is assigned to operator A, operator B can try to open the case via the search bar/accessing the team's worklist (looking for Operator A's assignment, which Operator B will receive an unauthorized message restricting the access.

However, when operator A tried to open the case or anyone for that matter, the case is locked by operator B and is locked for another 30 minutes. 

Anyone can suggest a fix for this?
