Decent - But Crashes Quite a Bit

Super frustrating that I cannot check into international flights via iOS app. After entering passport information from everyone, the app just crashes and Im returned to the home screen. Ill give frontier some credit for at least trying to integrate this feature into their app, southwest international flights just say to go to southwest.com on a computer, but I feel like the crashing made them miss the mark slightly.
