3. Why can’t I upload documents?

 There are situations when you are not allowed to upload your document. One of them is when you are using an old version of the browser (IE9 or lower) and usually you will get an alert like this “your browser does not support drag’n drop file uploads” case in which you will have to update the browser or use another one. Another case in which you cannot upload the requested documents is when the files you are trying to upload are larger then 60MB.
