On August 24, 2021 I was using the browser interface to add some files to a new Dropbox folder when I decided to cancel the process. When I went to look at the files on my hard drive, they were no longer on my hard drive. Not even in the "recycle bin". Dropbox needs to reprogram their upload system so this does not happen to customers. I will recommend to everyone I know that they not use Dropbox until the problem is solved.
