I'm about to submit an update to an app that's already on the App Store. However, I don't have access to the developer account that originally uploaded the app. So I don't have a provisioning profile that matches the bundle identifier. I do though have access to the iTunes Connect page and thereby the app's bundle identifier as well as App ID.
If I purchase a developer account, will I then be able to create a new provisioning profile / certificate that will allow me to submit updates to the app (based on the bundle identifier or App ID)? If not, what else can I do?
