You DO NOT release an update without checking for critical bugs. Especially if it is the main transport app in the city. If your developer team does this you have to change the developer to another one who have a proper QA department. The updated app logged me out of the system and kept crushing when I was trying to login. And with a ticket machine not working again on a station, it was the worst surprise for Monday morning. I’m using the app downloaded from AppStore of another country so you probably won’t notice this. So when I will change the region to Italy I will repeat this review so everyone can see this. Shame!
