Global search no longer including PO numbers

Summary:

When logging into Cloud, the search bar at the top would show PO numbers along with requisition numbers. This no longer is the case.

At the weekend (20th September) we took the 25C quarterly update. One of the things we have noticed since and has been reported to us by several business units, is that when searching for a PO number in the (global) search bar at the top of the main landing page, users are only seeing results showing the requisition number and they are no longer able to see the Purchase Order. I've looked in Setup and Maintenance at the 'Manage Global Search Configuration' options and within the search categories it only lists 'Purchase Agreements' and 'Purchase Requisitions' as options.
