Next time you can search the forum and find this answer. Google Pay will only work with certified final versions, never with beta ones. Until the beta is over, switch to Samsung Pay. It works just as well. When the final version arrives, you can continue using it or switch back to Google Pay.
During beta program, the software is not yet certified by Google, and therefore Google Pay and other secure services may not work. We apologize for the inconvenience and will post a notice once it becomes certified by Google. You may try again at that time.
