Steps to reproduce
1. Share a file, like a word document/excel spreadsheet.
2. Every minute the file syncs.
Sync once, and then stop syncing until a change it made to the file.
I've shared, and co-workers have shared individual files with me and the files sync every minute. I've seen it happen with three different computers syncing the same file between the three. You can't edit the file or modify it. There is no indication of what is going on.
