I have tried to drag and drop folders from my desktop into Dropbox app but it doesn't work. It re-creates the folder lacking all of the files. Then I have to go back and drag and drop each file individually which is an extreme waste of time.
Alternatively, when I try to upload via Dropbox.com, the upload time is ridiculous (over 1 hour for a folder of ~2GB). Yes, I have changed bandwidth settings for upload to not limit but it didn't help upload time.
Is there any way to upload multiple files to Dropbox app?
