I also have a very similar issue on my Samsung 5.1.1, today got in contact with city customer services on the message board and have been told that print at home tickets from Wednesday will be available. So I will contact City on Wednesday.Is anyone having issues with downloading the tkt to Google Pay? I'm using a Samsung S9 and NFC is on. Getting a msg saying cannot download to this device! S9 is hardly ancient. Any suggestions please?
