Yup. Look at train tickets in England. For now it's a convenience but you'll notice the law hasn't kept up with the push to have tickets on phones: the law still says you must produce on demand a ticket when requested. So if your battery runs out or your phone crashes or the app glitches or you've annoyed the "safety" department of Google/Apple... it's entirely your problem
A moody ticket inspector is under no obligation really to give you a few minutes to sort it out
Or, if like I experienced yesterday, the most popular train ticket app stutters during peak rush hour and you cannot display the ticket you have actually bought to the conductor and exit gates at the destination.
