I bought the Samsung A35 5g brand new and am experiencing constant issues with Google Wallet. Samsung don't want to know. My bank has removed all tokenizations. Google Wallet are trying to get to the bottom of this. Opened a new bank account with a completely different bank, but getting the same issue. Never had this on previous Android devices! Personally, think Samsung Wallet has blocked Google Wallet. I will be getting rid of this piece of junk soon and going back to Honor.
What is the csc of your device. If you head over to settings, then about phone, scroll down to software information. On the service provider software. Does it say EUX
I use Google wallet on my A16 with my NatWest card and have no problems with it at all. Did you try adding it from the card settings in the NatWest app?
This is in my quick notification settings, which means that Samsung definitely allows Google wallet. I use Google phone and messages app too, no problem with those. And assistant from Google. The problem you have is not Samsung blocking Google wallet
