According to the Control when app changes are published with managed publishing page in Play Console Help:
Managed publishing is only available for updates, not when publishing an app for the first time. If you want to use Managed publishing for your production launch, we strongly recommend publishing your app to a closed testing track first.
Keep in mind, internal test tracks are not covered by Managed publishing.
Assume I have published an app on a closed test track like alpha and this was successfully reviewed and published there. Does the above quote mean that I can promote the app to production and it is released immediately as soon as I publish it for the first time?
