Problem Gpay


Just to be clear:
1. have you installed Google Pay application?
2. did you tried another card?
3. what's the error message, can you post a screenshot?

Yesterday I installed on my Mi 8 the Google Pay application and I attached a Revolut card (Mastercard) and I already made 4 payments since yesterday.

1.Is installed
2. no because i haven't but N26 work with gpay
3.can not complete the payment configuration in stores. You can not use this phone for payments in stores. The problem could be caused by the presence of rooting or other alterations.
 
Is your device rooted or did you modified something on the /system partition like modifying the /etc/host file?
 
That's wierd, I have same configuration, but I do not have that issue.
Do you downloaded Google Pay from Play Store?
Anyway I cannot help you, unfortunately. :(
 
I think it's because you unlocked the bootloader, so safetynet is triggered. Try to install safetynet test and see if you pass the test
