Unusable with terrible functionality
Repeatedly logs you out. Required an update when we got to the station (I’d only downloaded the about 24 hours earlier) - had to update, updated, logged in again, I could see my bookings but it wouldn’t display them. If you have multiple tickets on the same train you can only view the QR for one one of them (and you don’t get to choose which!) and only add that one to your Wallet.
