I think Apple doesn’t provide pricing info because of privacy issue. For example user’s Region can be leaked. But you can submit price and currency while you verify purchases from user’s device, as an option. Another interesting thing when user upgrades or downgrades existing subscription, then you need to calculate pro rate values, which is extra developer’s obligation. I hope #Apple will provide some solution to get price info in transaction details (how much apple charged user) in a gently way. It definitely minimizes developer’s efforts and potential issues. Thanks.
