Three Peaks Challenge Shop

Throws an error and flat out doesn't export orders if the customer name already exists in Xero... Isn't that a pretty basic flaw? We have to manually add orders regularly. Why we have to pay for this amateurish app with no alternative options and Shopify don't make their own I've never understood. Thank you for your feedback. We sincerely apologize for any inconvenience this has caused. Our support team has reached out to learn more about the issue you are facing. We hope to get you back on track as soon as possible. Thank you for your patience.

Uninstalled because it clearly wasn't ready for use. It now throws an error on installation, yet Shopify are requiring it's installation by the end of October. Why is this going so badly?
