so I did the three-month-Premium-trial for 0,99 € from december to march and kept Premium. Last month I registered for Unidays and the Student Discount. However, although in my account it says I'm using the Student Discount, I still pay 9,99 € instead of 4,99 € monthly. Should I cancel Premium first and reregister directly for the Student Discount?
Thanks in advance for your advice.
