yep, increasing the prices goes hand in hand with changing the mobile website. Today the DB decided to again change their webinterface (which is browsed by ZugInfo). This means for the moment ZugInfo is broken and we are working on a fix. Sorry for the inconvenience.
[Update:] Alrighty then! Bugfix version finished, just needs some polishing (i.e. testing). Hope to submit it tomorrow. If I find the time over Christmas, I will try to implement a more sustainable solution for the website change problem.
[Updated:] Just submitted the bugfix to Apple (ZugInfo 2.1.2, Dec 13, 10pm). Keep you posted.
[Update:] Thanks to the swift work of the guys and girls of the Apple App review team ZugInfo 2.1.2 is now available in the App Store (Dec 18).
