No check-in possible - completely useless

At least for me this useless - as most people I would like to get a mobile ticket via this app. But the app does not identify the booking number. The website does but refers to the app when asking for a mobile ticket. Please learn the basics - all other airlines know how to do this....
And if you want to see something funny try the app support with an iphone and try to typr something in
