@CiaraNi I don't know if you saw my posts from months ago, but I actually forfeited attending a concert I'd paid for because of this.
I forget the name of the ticketing agency, but in order to use your ticket, you have to download an app to present at the venue. They won't let you print a physical copy. I didn't realize that at the time.
The only other option is presenting the credit card used, but it has to be in your name (it was in my wife's).
I refuse to play their game.
@analogfusion That's a great example of this kind of thing.
