Just purchased and made an airline. Can I ask, is it normal for it to constantly ask to create an airline with difficulty each time you start the App and select Airline Mode. I have done this, spent some money, but now in the red on Hard. Can anyone advise if this is happening to them? Also, the other issue I found was that it allowed me to hire a friend, then it gave an error "400" - my friend advised he did not receive an email.
