Observations​​: When our app calls the APNs API for push notifications, we observed significant fluctuations: July 15-25​​: The success response volume ​​increased by 20%​​ compared to the baseline before July 15. ​​After July 25​​: Success rates returned to baseline levels. July 30​​: Success response volume ​​decreased by 10%​​ compared to the pre-July 15 baseline. ​​ Excluded Factors​​: No changes in target audience size or characteristics (business factors ruled out). Server logs confirm consistent API request parameters and frequency. ​​Key Questions​​: Were there any ​​adjustments to response metrics​​ (e.g., success status code definitions) during this period? Have other developers reported similar issues? Were there server-side configuration updates or known incidents on Apple’s end?

For a period of time, we have frequently received reports of users receiving duplicate message notifications. We can ensure that the message is only sent once and there is only one ApnsId, but when it reaches the device, there are multiple duplicate notifications (2-3) I suspect this may be related to iOS 17, as there seems to be some overlap in time. Have others encountered similar problems? We sincerely hope to receive help from society. Thank you for your help~
