Copy‑Paste Fail: How the Bug Disrupts Workflow Excel users report that the familiar Ctrl+C and Ctrl+V shortcuts no longer transfer data between cells.

The disruption hampers routine tasks such as copying formulas, moving data between sheets, and sharing reports. Industry analysts warn that delayed data sharing could affect decision‑making cycles in finance and logistics sectors.
