Some of us offer critical service applications that each update can either be a risk of loosing service temporary on high volume of customers businesses, critical or sensitive updates to comply with local regulations or changes.
Sometimes changes are mandatory and out of the Developer's hands as we try to comply with each demands.
Question as follows:
What's the timeframe when you click "Submit" for approval (an application update, not approving the app for the App Market) and what's going on in the back end, why generally it takes 3-6 business days?
Like mentioned before, some apps provide a service that can't be interrupted, are the any tools or process to have this critical updates expedited?
This question is for educational purposes of new developers, thank you.
