I often (attempt to) use dropbox to transfer files from my laptop to desktop computer. Some days this simple process takes far too long. I just placed a simple 500k file in my laptop dropbox. The file says synced in dropbox. 17 minutes later in my desktop, the file still is not in my drop box which also says synced. I have looked at the trouble shooting guides and nothing applies or works. In my recent experience, the file will appear later today. Why is it taking hours to accomplish what should take seconds? PS_ This is a fairly recent issue this fall. All latest model Macs/OSX. After 19 minutes the file today appears in my Sync history on my Desktop Mac...yet I still can not access the file and it is not in my dropbox synced folder.
