Checking my phone now, I see that i don't have Google Wallet, and instead there is an unbranded Wallet that may be on my phone? Just, what the actual F? Are those the same thing? If Wallet is a generic thing on my phone, do I want Google Wallet, which Google Pay is telling me I should be using to manage my credit cards, now?
But the core secrets management and NFC handling app on your phone is and has been "Wallet", and the fact that you claim to be confused about that now is just evidence that you've never needed to use this UI because it Just Works.
The nonsense in this thread is about this "GPay" app, which is not and never was a payments management app. It was a peer payment service, itself based on Wallet. And no one was ever confused about it until they needed an excuse to yell on HN. They just didn't use it much, I guess, so it's been cancelled.
