Microsoft 365 Copilot [aka Office Hub] for Android or iOS auto-sends files to AI & OneDrive before you even realise it, instead of opening normally

Microsoft has quietly changed how Microsoft 365 Copilot works on mobile, and it’s going to upset most users. If you use Microsoft 365 Copilot as your default viewer for documents, spreadsheets, and presentations, and try opening any file, you’ll notice that Microsoft 365 Copilot now sends everything to Copilot. Worse, it auto-uploads files to OneDrive.

The Microsoft 365 Copilot app was originally called “Office Hub,” and it was a simple document viewer before it was upgraded with editing capabilities. This app has been around for a decade now, but it has undergone two major rebrands.
