Draft & Live
In the Vuframe Studio are always to versions of an app. There is a "draft" and a "live" version available. The draft version is for checking your content, before you publish it to the public live app. In a draft version you immediately see the changes that you have made in the Vuframe Studio. To see the content you have to make a content update.
To see the changed content in the live app, you have to release your changes. https://vuframe.com/docs/platform/studio/app-editor/app-publishing
