i have the google pay app and have added all my cards.
i currently want to use it with amex and have set that up as the main card.
however every time i try to use it in a shop i get a transaction error and it doesn’t work. this is in shops that accept amex as well as mastercard and visa.
what’s weird is it’s definitely set up correctly as when i use my amex card normally i get an instant google pay notification on my phone (not sure how google pay gets this information but still).
how on earth do you actually use google pay on android? all the instructions i’ve read say just open the app on your phone, turn on nfc and then touch the reader like a normal contactless payment. why doesn’t it work?
