date-selector doesnt work on iphone 6

app is not working, again a non-functioning app, ...why Hilton, as a global company, is not capable of getting a simple app right ? earlier versions ask for a title when trying to book, this one doesnt go back to the booking process once selecting other dates than given ones.
lamentable.
