Word kept saying me it can't upload changes. I was like OK I can just save as to my OneDrive folder.
It saved it to the folder and then I closed Word. When I re-opened it it turns out this piece of **** never actually saved it. The interconnection with OneDrive is broken and nobody should be using it.
I have checked the autosave files, and version histories of OneDrive but there is no late version of my document. In fact the latest version is from two days when I last edited it.
I advice nobody to rely on Microsoft's pieces of **** cloud software.
