I am having sync issues. I was on my desktop and changed the name of a file. I went to my laptop and my other desktop a few days later and the new file name is not showing up. It is still the same old file name. It shows up as a new file name when I go to Dropbox online though. What can I do, besides restart my computer which is not solving the issue, to get the file to show up under the new name? Thanks!
