Thank you very much. I have shared the device token information via the link you provided. I will wait for their response from there.

Apologies if I came across as pushy. May I ask about the current status of the response regarding this matter? Thanks

Thank you for your response. We will make every effort to add apns-id logging functionality as soon as possible. Before we proceed with sharing the device token, we would like to confirm whether it is appropriate to post it in this space. We are concerned that someone with access to this thread might misuse the token to send unauthorized push notifications. If you recommend sharing it via email or another secure method, please kindly let us know the preferred way.

Dear Argun Tekant Thank you for your response and for the helpful insights. We have determined that the notifications should have been successfully delivered but were not received, based on the following information: Our server received a successful response from APNs when the notification request was sent. The user has confirmed that notifications are enabled for our app on their device. The user reported performing the action that triggers the notification three times, and on all three occasions, the notification was not received. → Based on this, it is unlikely that the issue is related to network connectivity. The user also reported that the app icon badge did not appear on any of those three occasions. Unfortunately, we did not set the apns-id option at the time, so we are unable to provide that information. Would it be possible to investigate the issue using the device token and the timestamps of when the notifications were sent? We appreciate your continued support and guidance. Best regards, Ryo
