Studio will automatically save all changes made by all editors, and generate a new version for each change. Click History to open a panel listing all versions of your App. Listed versions will show each version’s editor, and its age.
Click on a version to select it, and refresh the preview display in the right pane. Click Restore Version if you wish to clone the selected version, and begin working from it. Click the back button in the Version History pane to revert to your working draft. Click Share to generate a URL for the preview, which may be sent to co-workers or friends for review.
Note: Your App may not be edited while the Version History pane is open.
