Hi there,
I acquired a Pixel 6 Pro last year and have been dealing with a reccuring issue with Google Pay/Wallet. I have two different cards set up on the app. One is for paying for fuel for my car, the other one is basically anything else. I set the "Anything else" card to be the default card and for whatever reason, the app keeps changing it to the fuel card. Googles support was pretty useless tbh. Basically just told me to reinstall the app. Issues still occurs. Someone help me pls
