My Flights doesnt work on iPhone 5s

App has nice features, but the most important one, showing itinerary and status for my flights asks to find your trip by confirmation #, credit/debit card, or ticket #, yet doesnt let you enter a value! Tapping in the search field brings up the three choices you can search by, but no keyboard to type in a value or even access to the field itself.
Can only guess this is an iPhone 5s bug in the app.
Disappointing!
Tried adding my trip via the website which worked, but the trip still isnt showing up when I go to My Trips in the app.
