Version/preview

How can I change the version number? I already have a gold membership and inserted all the push API information but it doesn’t let me change the version number because I need to upgrade first.

I assume the large preview window is now the correct live preview of the app because the appery.io window/red button is not there anymore. Is that correct or a bug?
