Compulsory app that doesn't work
I always wonder why big companies have their apps designed like the were from 2008 yet never test the usability OR functionality. Even less of they are the only way for let's say - boarding a ship. Incredibly unflowing UI. No state saving in big forms, overlapping data input fields. Missing fields for required input (don't know if that's funny or really sad). PLEASE buy your software from trusted, big enough companies who keep their skills up-to-date.
