Subject: Urgent Issue with Mobbin Challenge Promo Code

I want to raise a serious concern about the Mobbin Challenge promo code. Many users are unable to apply the code even though it appears valid. The checkout page repeatedly shows that the order does not qualify, which blocks participants from accessing the challenge benefit. Because of this issue, many interested users are unable to join the challenge, especially new users discovering Mobbin, who already need time to understand the platform & learn the tool. Since the challenge timeline is already short, this problem further reduces the time available to explore the platform & prepare projects. I kindly request the Mobbin and Contra teams to urgently review & fix this issue so eligible users can activate the benefit and get a fair chance to participate and submit their work.
