Deployed Sharepoint Add-On (former sharepoint App) to Production

when we move sharepoint Add-On to the production, we try to use the package in the QA and uploaded it to the app store in the production enviroment.

After create a page, and added the add-on via the web part on the host page. save the change, then reload the page, but web app is reference to the QA host.

we must repack the sharepoint with the live URL of the web app, so that we can have the sharepoint Add-On with corrected path to the Live Web Application.
