The Nominal Discount from promotions is not being distributed among all items in the cart.

This scenario is happening only in a few accounts.

The store has a nominal promotion and the discount is only being applied to one item in the cart, not proportionally distributing the discount to all the items like it is supposed to.

1. Create a regular promotion with a nominal discount;
2. Create a cart link where the promotion is applicable;
3. Check that the discount is being entirely applied to just one item instead of being distributed among all items.

PS: This doesn't happen every time and with every account.

To mitigate this issue, you can use the API Create or Update Coupon API to increase the maxItemsPerClient field. This allows the coupon to be applied to as many SKUs as permitted in this field.
