Welcome to the Community, @SMNK Digital Media!
Can you please let me know what’s the current syncing status and app version of your Dropbox app?
Are you only having this issue with the Dropbox app on your computer, or with other third-party apps/websites, too?
Are you able to see your current uploading speed, if you hover over the small Dropbox icon in your system tray/menu bar?
Let me know.
