Cant check-in or add my flight info

Worthless app. Looks pretty but cant do anything. Every time I try to add a flight or do a check in it tell me to go to the front desk! Definitely not a time problem since Ive already checked in from the web and have my passes ready to go. But this app still wont recognize my flight info
