I've registered as a iOS company developer. And I've been able to give access to my developer (from Manage Users/iTunes Connect User/Technical role, I've even tried giving Admin role) but he does not seem to be able to register bundle identifier (which is required to 'Add New App'). I can register the bundle identifier myself, but the app is being developed remotely and I want the developer to be able to manage apps himself.
Many thanks.
each developer must have his own developer account and must be in your team. if they dont have an account, they can sign for free, they dont need a paid account. then you can invite them to your team and you can assign the rights.
