Hello, @Engineer Thank you very much for investigating this so quickly. I understand that the root cause has been identified and that a fix will be included in an upcoming iOS update. We appreciate your efforts and look forward to the fix. I also understand your explanation regarding the behavior of invalid tokens and the fact that the timing of receiving a Status 410 error is intentionally non-deterministic and will not change. To help us explain this issue to our app users, I would like to ask a few additional questions: Which iOS versions are affected by this issue? Under what specific conditions does this issue occur? In particular, we would like to better understand the situations in which an old token may still be treated as valid after the app has been uninstalled. Thank you for your assistance.
