Duplicate discounts on Shop Pay checkout

Update timeline

1. identified Aug 25, 2022, 05:42 PM UTC

   We've been notified by Shopify that their development team is currently addressing an issue with critical impact that is affecting the Shop Pay checkout. This issue causes product-level discounts to be duplicated at checkout, causing a discount higher than the intended one. This issue is limited to checkouts that happen via Shop Pay. Shopify's development team is working on a fix. It is unclear at this point if this affects all customers or not. If you are running promotions with Discount Ninja, we advise disabling Shop Pay (https://help.shopify.com/en/manual/payments/shop-pay) while we wait for Shopify to fix the issue.

   Waiting for feedback from Shopify on this issue. Lowered the impact to minor because a workaround is available (disable Shop Pay).

   We are continuing to follow up with Shopify regarding this issue. We have been informed by Shopify that their product team has been working on a fix for this issue since August 24th. Unfortunately, we currently have no information on when Shopify will be able to release a fix for this issue. Please note that there are two workarounds possible for Discount Ninja users: - Switch of ShopPay temporarily until this issue is fixed by Shopify (https://help.shopify.com/en/manual/payments/shop-pay) - Use Discount Ninja in “Discount code mode” (in the menu of the app go to Settings > Checkout options)
