I'm having trouble with a file in my Dropbox which I frequently amend. If I download it to my WIN10 account there is no problem - the latest version is brought up, and if I amend it the latest version is saved. If I look on my Android system, the file list shows correctly that the file was updated a couple of days ago, but the file that is downloaded (a Word file with the save date shown in the header) is that for last July, 8 months ago. It is always the same, old, version that is accessed.
What's going on?
