Until about last week I could upload multiple files using Document Cloud > Share Files > Computer > drag & drop, and create one link. Now it won't let me upload more than one file. Even if I upload one file, the link that used to show up in the lower-left corner saying "add a file" (or "add files" or something) isn't there anymore. If I try to drag&drop more than one file, I get a warning as shown in the attached image. A critical reason that I subscribe to this service is to be able to upload multiple files (not all PDFs) into a single link to share. Please return this functionality.
