4. For Google Wallet/Pay Linking Issues:
- If linking fails, check your settings in the Google Payments Center (web version). Make sure "Share that you have Google Pay with companies outside Google" is enabled. This setting can prevent linking issues between Kris+ and Google Wallet.5

5. For 2-Factor Authentication and Login Issues:
- Kris+ uses 2FA at first login on a new device. Make sure your registered email and mobile number are correct and accessible to receive the One-Time-Password.3
- If you encounter trouble with 2FA, check that you’re entering your information in the correct format, especially your phone number.5
