How do I view the existing coupons applied to my CEP account?
In Settings >> Coupons and Referrals, you will be able to view all codes at the bottom.
"Code Status: Redeemed" means you have already used the discount code.
"Code Status: Open" means you have not utilised the code yet, and it will be automatically applied based on it's functionality (i.e. if it provides you with a $30 platform renewal credits, this will be automatically applied and utilised at your next subscription renewal. For example, if your subscription fee is $899, only $869 will be deducted from your payment card).
You can click on the code itself which will give an explanation what the discount code entails.
