Check my post;
The error only happens on google pay, out of nowhere, I finally was able to put my credit card directly and since then I been able to use the discount codes, contacted on friday support still have not received a answer from them or any mods on the forum, for me it was a $35 dollars I lost believing it was getting discounted. Pretty sure this issue should be fixed as soon as possible because it may fall under scam since u do see the discount applied and when u pay if u check the transaction instead of waiting the code, you don’t see it anymore the discount which people only realize after purchasing item, not before purchase.
