Quick guidance for Promo Codes
You have to go and click the Usage&Billing tab from the left bar in the portal. Once you've done it, there will be a section for promotion codes.
And then all you have to do is click the "Apply code."
Upgrade your account to a Scale plan to be able to apply the promotion code.
