Dead-end at test app creation

For future reference, there are many different topics on the general support forum, but the correct one for developer support (but not ‘wix code’ support) is: Wix Developers Login. I know this because I was helped on the ‘general’ support forum (Wix Support, not sure if these tickets are public), but they told me that I needed to use the devforum one for these kinds of questions in the future.
