I am using 2.2.3 version for iOS using swift and UIKit. My oauth is working fine. Reader is getting connected. But as soon as I put on card of square contactless reader. Popup appears Payment Failed. The payment could not be completed. Please try again.
Also delegate method for payment failed is not getting called.
Please help,
Payment Did Start: [“createdAt”: 2025-05-26 12:46:35 +0000, “totalMoney”: $1.00, “sourceType”: “UNKNOWN”, “amountMoney”: $1.00, “status”: INITIALIZED, “updatedAt”: 2025-05-26 12:46:35 +0000]
