Can’t find any information about original_transaction_id in Family sharing. Can anyone say will original_transaction_id one for all members who get a subscription with Family sharing or original_transaction_id will be unique for all users? I need determine all members from all Family Sharing to give them ability to use the same data.
Here is answer that i got on apple support forum:
They will each have a unique Original transaction id, the StoreKit transactional data does not support identifying a family cohort. We welcome feedback to share with the teams. FeedbackAssistant.Apple.com
