I also filed this issue through Feedback Assistant (FB24533921). The feedback has now been closed with the resolution “Investigation Complete – Unable to Diagnose with Current Information.” However, I wasn't asked to provide any additional information before it was closed, so I'm not sure what information was missing from the report. Could you please let me know what additional information would be needed to diagnose this issue? For example, if logs, a sysdiagnose, a StoreKit diagnostic profile, or a sample project reproducing the issue would be helpful, I'd be happy to provide them. I'm also still trying to determine whether receiving multiple transactions with the same transactionId from Transaction.updates is expected StoreKit behavior, or whether this should be treated as an issue to investigate.

I have submitted this as a Feedback report: FB24533921. Thank you for your attention to this matter.

Thank you for your guidance. I have collected the sysdiagnose logs following your instructions and submitted them through Feedback Assistant. Please let me know if any additional information would be helpful.
