I am using your free option of your service and I am teaching high school students how to build an app. we are going through your tutorials one by one we are now getting to your tutorial on Versions. It looks as if we can not complete that tutorial since I am only allowed to have one app at a time and in Versions it ask to create a second or am I missing something.
Secondly if we can not complete it due to our account status are there any others we will run into this problem again?
