I have a number of excel files on my computer that are constantly syncing, despite the file being unchanged. I sync to a read-only version on a remote desktop that I control, so I am fairly sure the issue is on "my" end. In my experience this is only happening with excel files. I made sure the timestamp was updated, having seen that cause problems for other users on the forum. This is an instance from the error log. It will occur repeatedly, sometimes preceded by a "ping" or a "Extension:" line.
