I hope this message finds you well. I am writing to bring to your attention a persistent issue that we have been experiencing since January 12, 2024, at 4:05 AM（JPN）. It appears that push notifications are not reaching some iPhone devices in our user base.
We have taken the following steps in an attempt to resolve the issue:
1.Checked the notification settings on the affected iPhone devices to ensure that the app is allowed to receive notifications.
2.Verified that the app is updated to the latest version on all affected devices.
3.Restarted the devices to rule out any temporary glitches.
4.Uninstalled and reinstalled the app on the affected devices.
5.Ensured that the devices have a stable internet connection via Wi-Fi or mobile data.
Despite these efforts, the problem persists. We suspect that there might be underlying issues related to the push notification service or other technical aspects.
Could you please assist us in investigating and resolving this matter? If there are specific logs, error messages, or any guidance you can provide, it would greatly aid our troubleshooting process.
Our users greatly depend on receiving timely notifications, and we want to ensure that the service is working seamlessly for everyone. Any insights or assistance you can provide to resolve this issue would be highly appreciated.
