I always get an "upload your art now" email but when I'm about to upload it says something like "Sorry, we're working on improving the structure of this section to simplify your experience. As a result, you won't be able to upload new artwork here for a while. We'll let you know. you via your registered email after the reshuffle is complete". and previously I've downloaded my work and it's still in review and now when I want to download it can't. why?
