I'm moving from my paid iOS app to a subscription model. I synced the build number of the paid app using the purchaseHelper. https://github.com/codykerns/PurchasesHelper
CompatibilityAccessManager.shared.syncReceiptIfNeededAndRegister(entitlements: :
.init(entitlement: "premium", compatibleVersions: r"1", "2", "3","4","5"])
])
How can I test that existing paying users are converted to Premium before releasing the app?
If I buy a paid app on my device and update it to a test flight, will I be able to test it?
