MLB Ballpark App: A History of Bugs and Unreliability

I posted this because it took me 2 hours to purchase a ticket to a spring training game. What an absolute disaster this process of buying a ticket is.

I swear if I need the app to park I'm turning around and charging the ticket back.

Edit - I charged it back, the app wont take my email.

Being required to use an app to go to an MLB or NFA game is a no-go for me. Why is a QR code insufficient?
