So... went out and got a WearOS 3 watch and got pretty much everything to work without a problem except that I cannot seem to add any HK based Visa/MC cards to the wallet - Amex worked perfectly.
- HSBC EveryMile / Red - they've switched to some in-app authentication and can only add to the phone wallet, cannot add it to the watch wallet.
- SC Cathay - They don't have their own app based auth, but their SMS auth seems to work only on the phone wallet.
- Citi (some rewards card..) - Same as SC
Has anyone been able to add a Visa/MC to their WearOS / Google Wallet? Not Samsung.. not Apple... Google WearOS.
Have not really bothered calling the customer service hotlines as I suspect this is a rather obscure issue for which I'll get the run around and/or might crash their chatbots.
