I have contactless payments set up via Google wallet.
My new Fairphone 5 is great with contactless payments, unless the point-of-sale machine in question is of the Sumup brand (the little white square card readers). When I try to pay via contactless to a Sumup card/contactless reader, I get the “Payment approved” notification on my phone, but the machine declines the payment.
Is this a known issue? Is there anything I can do to address this?
