Dear StoreKit Engineers,
I recently migrated my app to freemium model from paid and am using AppTransaction to get original purchase version and original purchase date to determine if user already paid for the app before or not. It seems to be working for normal AppStore users but I am now flooded with complains from VPP users who previously purchased the app. It seems AppTransaction history is absent for these users and these users are asked to sign-in using Apple ID.
What is the solution here?
