Unable to upload PDF files on UpWork to share with clients

Hello,
I am trying to upload PDF files, but unable to upload it.
How can I share PDF files? 
I have to use the dropbox for this small task and then generate the link to share it with the client. 

What's the matter with UpWork for uploading the files, kindly guide me
Thanks
Shahzad
