Haven't had issues until recently my myki ticket number has disappeared. I got the number cancelled and refunded, confirmed with both PTV and Google the card number was deleted on both ends. Went to generate a new one, and still not showing a ticket number and it won't touch on, yet the money has been deducted. I've contacted Google at least five times, to no avail. Can only blame one of the more recent updates, although it has been happening for a few months now.
