I have Microsoft OneDrive on all three of my computers. On one computer the drives are up-to-date as this is the platform that the files are worked on. The other two platforms have the OneDrive folders on them, but they are older versions. It seems that the other two platforms are using the files when they were originally created - up to 12 months old. If this product does not work - synchronise files, why is it offered by Microsoft as a way to access files from all platforms?
