1 year agoEnter the correct PRO version of the 30-digit serial number to get the discount (trial procedure)
As you indicate, "The coupon code you entered is invalid. If you have any questions about this, please contact the issuer."
Possible mistakes include "Entering the bundled serial number for Wacom distribution" or "You have used discount rights in the past".
How about contacting official support? Https://support.clip-studio.com/zh-tw/- Japanese
