MIUI 8.5.4.0 (MAGMIED) - Device not certificate

[J4s21gp]

Hi!

I have a new Xiaomi Mi5S. I received a new OTA ROM, MIUI 8.5.4.0 (MAGMIED), Android 6.0.1 Mxb48t. However, I have a problem. In Google Pay, my device is not certificate. Any idea? I have tried factory reset, clean datas Google Play, Play Services, etc...

Thank you

This is weird, do you have it rooted or unlocked?
Maybe you could try to flash it again with Mi Flash with the option of locking it again (flash + lock).
