Latest version crashes – Selfycart - Mobile Self-checkout Review

Using May 17th release on iOS 10.3.2, iPhone 7+. On my last three trips to bfresh in Somerville, MA (I stop in almost every day), the app crashes a few seconds after completing payment via ApplePay. To get validated, I must restart the app and reload the code from my latest receipt. Just a few minutes ago, I tried to send you this information using the Feedback page in the app, but it crashed again while I was typing in my comment.
