For all the fancy colab features Ill never use, dropbox still utterly fails at basic file management - try moving more than 10 or 20 files at a time - if it even succeeds it will take around 1 second per file. Try moving 5000 photos from camera uploads?! The app will always fail, and even a browser on a PC may or may not succeed and if it succeeds will take hours to complete. Brought this up with tech support years ago, still nothing has changed. My QNAP home NAS and apps works much better!
