Hello @Nish_14 ,
As mentioned in the thread - sadly Google Pay won't work on Beta software, but it will work when the stable version is released. If you would like to continue using contactless payments during Beta Programme, you can still use Samsung Wallet instead of Google Wallet 😉
Have a good day!
If I'm currently using Beta, once the stable release is ready I just need to update and this update will remove the Beta. Or should I first leave the Beta and then Update?
