The file upload icon is one of the latest innovations added to PageProof. It is found at the top right of your dashboard screen, beside the notification icon (the bell). It appears and displays in green if files are uploading and will disappear once the upload is finished.
Click the file upload icon to see the status of each file (proof files as well as comment attachment files).
You can upload a number of files and leave them uploading whilst you navigate around and do other things in PageProof – just don’t close the browser window when it’s happening.
