We are encountering an issue where Apple Pay shows an unexpected popup with a <Title> message and an "OK" button when confirming a payment (after double-tapping the power button). This issue began appearing last week without any changes to the codebase or configurations.
Steps to Reproduce:
Open the app and initiate an Apple Pay payment.
Add a valid card if not already present.
Confirm the payment using the side button (double-tap).
Instead of completing the transaction, a popup appears with a generic message and an "OK" button.
Expected Behavior: Apple Pay should process the payment and provide a confirmation or error based on the transaction status.
Actual Behavior: A popup appears with a generic title and an “OK” button. The transaction is not processed.
Environment Details:
Platform: iOS
Apple Pay integration has been functioning correctly for years
No recent updates to Apple Pay-related code or configuration
Configurations Checked:
App Identifier is correctly set with the bundle ID
Apple Pay Payment Processing is enabled in the App ID configuration
Correct Merchant ID is selected and matches in Xcode capabilities
*.entitlements file contains correct Apple Pay entitlement
Payment Processing Certificates are valid and in place
Additional Notes: The issue appeared suddenly without any modifications to the app. We suspect it may be due to external changes (e.g., Apple system update or merchant validation issue).
Please advise on any further steps we can take to diagnose or resolve this issue.
