CodeCanyon UserName Change Issue

Hellow, i wana change my username on codecanyon from “rifat636” to another. can anyone pls tell me, did it can affect on my product, backlink, or other’s

Your profile URL won’t be affected, the URL of your previous username will just redirect you to the new one, nothing to worry about. But your referral links will no longer work, you’ll have to change them manually one by one to get them working again.

if referer totaly not work’s or work’s but dont show my reference

The link itself will work, but you’ll have no benefits from it (I mean if someone clicks on it and buys something, you won’t get that 30% cut), unless you update it to make it match your new username.
