Abnormal Invoice Approval Behavior

Hi Oracle Fusion experts,

We have been experiencing abnormal invoice approval behavior since last weekend (27 June 2026) and are wondering if anyone else has encountered the same issue.

Observed behavior:

• An invoice is created and submitted for approval.
• The manager approves the invoice successfully.
• Instead of showing "Approved", the approval history displays "Acquired By" under the Action column.
• One day later, the approver receives a reminder email with the subject:
  • FW: (Reminder) Claimed: Approval of Invoice XXXXX
• Another day later, the invoice status changes to Released and appears back in the pending approval worklist.
• If we attempt to force approve the invoice, it is routed back to the approver again.
