I recently opted for an e-ticket as an experiment, on the back of information from this website and a number of other sources, about how versatile, flexible, and easy to use they are. I bought a TransPennine Express Only Advance ticket from their website (the only place it was available from). Unfortunately, the email which I received said this: Unfortunately when I go to their app and open the tickets tab, I don't get my ticket (I was already logged in), I just get a loading screen and then this error message: I have tried several things and none work, including uninstalling and reinstalling the app. The phone is correctly connected to the internet, and the app can access the internet, because it can do a search for live departures right now. My device is an Honor 10, so while plainly it is not the top end of the Smartphone market it is not anything like too old or low-end to handle their app correctly. My only thought is to call their web support and ask for the ticket to be changed to collection at the station. If they won't agree to this, I wonder if they will formally permit me to travel with only a confirmation email? Obviously I won't be agreeing to buy a new ticket. Needless to say, I now have a less positive impression of TransPennine Express, and I am unlikely to be using any more so-called "e-Tickets" again soon. Suddenly I feel more like @yorksrob !
