(BE AWARE) I logged in after a few months of inactivity and noticed unfortunately 5 of the course certificates that I fully completed and printed years ago, some of which had dates, were somehow reset to 0% and I alerted support because the dates on certificate matter to me ... I needed the dates for when I ACTUALLY completed them years ago!!. This has made me lose hope in udemy. I will NOT buy another course to have it cleared again and get no real help.
