We are updating our app and would like to temporarily unpublish it from the app store so that new users don't find and download our app. Is that possible? And if we unpublish the app, is it easy to get it added back to the store? Will we still have access to our app store assets and content?

Is there a way to add a message to our app's log-in screen when the app is not available for users?

Our app name is one word, but when searching in the app store, it requires a space between part of the name. I've checked our store listing, but I don't see a space in the name. What would cause the need for a space in search? Could there be an issue in the app code?

We are going through a rebranding of our app, and need to update the developer name that displays under the app name in the app store. Is that possible? And if so, how do we do that?

We're going through a rebranding, which will affect the name of our app. Everything else about the app will be the same. Do we need to create a new app store instance, or can we modify our existing store with the new name and preview images?
