Improved stability on SCI and pre-paids

Based on our merchant feedback, we’ve made strides in improving the stability of the billing process for merchants using the Shopify Checkout Integration (SCI). The previous implementation would occasionally surface errors when a shopper was checking out while the system was processing recurring orders. With the most recent updates, the team has kept error mitigation and a seamless customer experience in mind so processing recurrent orders will be less likely to cause an error, especially when multiple customers are attempting payments in a store. 

We’ve also rolled out general stability improvements for pre-paids.
