Hi!
@ MEB, I have the same problem as torkjellmidtgaard. I'm on a iPad pro, but I use a danish version of iOS. If I try to set the language, as you told torkjellmidtgaard the app just quits. So it is not possible to try to set the languarge i the app. I guss that you enter the preferencer by the cogwheel in right upper corner.
I'm looking forward to try the app out. The tutorials looks great.
Edit: after I selected English as a iOS language, I was able to set the language to English, in the app. It was set to Default. Now the app doesn't crash after I reset the iOS language back to danish.
