Hi there,

Hi I tested demo on PayPlans and added a ref code Ref33 and then tried to use it when register...

I do not understand your inquiry well. I believe PayPlans referral behaves differently where the referrals are basically another form of discount in which a user shares a code to others so that they may use it to apply discounts. Perhaps, you can read more on our documentation on how referral works.

However, if you're referring to another functionality, kindly explain more so we could understand you better.

Thanks.
