    We are using Paypal Express Checkout V1.12.0 in Woocommerce 6.3.1 and have issues with coupons. When a customer uses a coupon (e.g. 20% off), he is not able to complete the purchase with Paypal Express. Regular Paypal checkouts are not affected.
    The debug log shows error 10431 “Item amount is invalid”.
    For a coupon item the log shows [L_PAYMENTREQUEST_0_AMT1] => -4.20168067 whereas regular product items have only two decimal numbers.
    Could this be the root cause? If so, is there a way to fix it.
