Thanks for keeping me posted @bedford351.
Could you please provide a screenshot of the exact message your app is stating at the moment?
Kindly note that syncing is a core functionality of Dropbox. For as long as there are changes made within your Dropbox folder or your files online (including shared folders) the desktop app will normally sync the changes so the "Syncing" status is normal since each file is divided and compressed into hashed components, transferred via secure data transfer, and then encrypted and stored on our servers. When uploading, the transfer speeds can also depend upon how quickly your computer can process and compress the components of the files to make them available for upload.
Another thing to note here is that all of the Dropbox servers are located in the US. Your connection speed to Dropbox is highly dependent on the routing you get between your Internet Service Provider (ISP) and our servers, and may be slower than your ISP's rated speeds.
As I would really like to have a further look into this, could you try testing your speed using the following bandwidth test and let me know what you find? This will test your ISP connection speed.
Thanks for taking the time to go through my suggestions and your continuous cooperation on this one!
