I have a question about the build for iOS and Android. I recently lost the sources of an application I developed on these two platforms, but apps are already in stores. I questioned Apple's support if it would be possible to program the entire application again and update the current version without losing update history, download history, comments, ratings, etc. They are not direct and every email I receive is even more confusing if you can or not. I would like to know for the case of Android too, as I do not even know how to find this information in an 'official' way. If possible, please indicate some sources from Apple itself and Android, please - I need arguments in my company.
