Transaction.updates
When testing on TestFlight, Transaction.updates emits payments that occur on the same device (usually within 1min after payment is finished), contradicting the docs:
The asynchronous sequence that emits a transaction when the system creates or updates transactions that occur outside of the app or on other devices.
Transaction.unfinished
When testing on TestFlight, Transaction.unfinished contains finished payments from a different device (same App Store account). Docs:
A sequence that emits unfinished transactions for the user.
Both issues do not happen when testing with Xcode.
Xcode 15.2, iOS 17.3, 17.4
