Non-Shell branded cards not accepted – Shell US & Canada Review

On iPhone 8 iOS 13.1.3 the issue has not been resolved and I cannot add any credit cards other than Shell branded cards or ApplePay. Please fix! Love the app otherwise but these bugs are annoying. Additionally not showing the number of cents off per gallon I get based on my Fuel Rewards account.
