I started downloading three games yesterday so I left the PS4 in Rest Mode.
Now I'm at work and I'd like to see the progress but going to https://store.sonyentertainmentnetwork.com/#!/en-us/download/queue results in an empty list...
If you start the download from your console it will only show the progress from your console.
The only way to view the download progress from the PlayStation website is to push the download from there. Once you have selected to push a download from there the web site will display if the software is waiting to download or in the process of downloading.
