We have version 2.4 of our app already gone live (Ready for sale) in app store. We planned a new update 3.0 to be released on 28th March and it is Apple reviewed and in Pending developer release state, but there is a new feature we need to add to the app. We have created a new build but we do not want to reject the 3.0 because it is already approved and we have to go live something on 28th of March. There is a risk of Apple will not approve the new build in time (we have 6 days to get the approval) if we cancel 3.0 and re-submit it.
How can I submit a new version (lets say 3.0.1) or change the build of 3.0 without removing approved 3.0 build?
Thank you.
