Adding checkout discount on the code

[MohsenNMZ]

Hi, I am using Shopify on the flutter app. I was using this syntax to add the checkout code:

shopifyCheckout.checkoutDiscountCodeApply(
            checkoutId, _discountCode);

Since last night it does not appear anymore on the checkout page and customers need to add it manually.

It happens to us exactly the same, since last night we cannot do this process, and we have many users asking about the error.

The problem got solved by the Shopify team and it is working now.
