When you use referral links, for example mine: https://www.labymod.net/shop/ref/GXJ28Z
nothing happens. When you click on redeem and enter the code it just says "Code not found".
I also tried it with https://www.labymod.net/shop/ref/reved and that works.
Operating System: Windows 10
Browser: Opera GX
