A Microsoft file hosting and synchronization service.
We tried to mitigate the issue by having my wife create a new folder and sharing it with me, but now I cannot add the new shared folder to my files! I get the error message "1 shortcut wasn't added".
This is appalling. Something that worked for years without a problem and Microsoft just break it. No explanation, no information if/when a solution may be found, just intolerable silence. If we don't get a fix soon I will cancel our onedrive subscription and move to Google Drive instead.
