Why can't I link Google Wallet to my Xiaomi Band or Xiaomi Watch?

If your Google Wallet can’t link your Xiaomi Smart Band or Xiaomi Watch recently, please assure you that this issue does not signify a failure of the product itself. Instead, this problem is due to the recent update to the Google Pay APK. After completing this update, please allow a whole day for the linking process to finish successfully. We kindly ask that you try linking your devices again the following day. Thank you for your understanding and patience during this time!
