Followed the app's instructions to go to gate 15, sat there waiting for the gate to open, until eventually getting a notification that I'd missed the flight from gate 30. Went to the help desk, was told that since I was the only person who made that mistake it was clearly my fault rather than the app (which was still displaying the wrong gate, even while I was at the help desk). Got booked on a $400 replacement flight for a journey which was originally $50. In the queue to board the replacement flight, I meet around 20 other people who missed the same flight for the same reason, all being told "it's clearly your own fault, ryanair has no responsibility here"...

Where are Ryanair flying that you paid in dollars?
