Delete a Visual Application
If you no longer need a visual application or a particular version of it, you can delete it from the Home page at any time during the development lifecycle. You can also permanently delete an application to completely remove it from the system.
It's especially important to delete obsolete versions of your application, created when a published version is superseded by a newer version. If your app has 100 versions (the maximum number of versions an app can have), you won't be able to create new versions until you permanently delete some versions to stay within the version limit.
Caution:
Permanent deletion of an application cannot be undone. It completely removes application metadata and any data stored in its database. Before you delete, consider the impact of deleting your app, especially if the version is live. While you still have a chance to restore the app within 30 days of deletion, once a version has been removed from the system, it cannot be recovered.If your teammates have access to the apps you want to delete, you might want to remove them before you delete the app. Use the Team tab in the app's Settings editor to remove access.
