It was recommended to me to get the gate numbers earlier than the boards however 2 recent wrong gates from the app have led me to be very wary of it.
The most recent had me nearly at the 300 gates ( from the app ) when the boards changed to a 400 gate . The app had not changed to the 400 gate by time of switching phone to airplane mode after boarding.
Bugs me when you have your flight marked as a favourite so you start getting notifications but the text is too long so you can't see what detail of the flight has changed. It's usually either that the gate number has changed or the flight is now marked as delayed by 10 minutes or so but you can't tell from the notification message. Never had a problem with wrong gate number.
