I am trying to grant access to users that subscribe to premium on the iOS app also to users that use the macOS version. The iOS and macOS version are two separate apps with different BundleIDs, same Team ID. I can't create a App bundle because they are part of different platforms. I know that I could ask the user for a login so I could recognize the user from the authentication, but I would like to avoid this step. Is there any ID i can use to identify users between different platforms?

Hello, is it possible to change the account holder of a membership signed as "Company / Organization"? Is it possible to change the agreements to another member of the account (admin)? Can a developer account (company / organization) transfer apps to an individual account?
