Unable to push notification to specific iOS devices

I'm using Apns, but
In case of 4G communication on a particular terminal (the settings of the terminal are adjusted to other terminals), I did not receive any notification.
If you are using Wi-Fi on a particular device, you have received a push has arrived.
Push notifications have been received even if 4G is used on other devices.

Why can't I get push notifications to specific devices?
The device settings are included, but please let me know if there is any reason you know.

The comment section is hard to read, so I will add it here.

1. For development purposes, an application with an older version is installed. 　　→ No installation has been performed since the certificate was changed.
　　→ Production or debugging, throwing mismatched notifications

I have verified that the latest application is installed.
I think there is no problem because it was installed a few days after the certificate was changed.
The notifications are in production.

2.Mismatch of saved tokens

On the server side, I checked the application logs and confirmed that the tokens match.

3. High number of simultaneous transmissions (maximum number of bytes transmitted)

The number of terminals sent at the same time is three, four characters in the title and four characters in the body.

4. Do not allow notifications

Allow notifications and set the notification style to banner.

5. Poor connection

Carrier communication was in good condition.

Setting the iPhone's device settings Notification → Notification style (per app) → Notification style when not locked
After setting from Banner to None, you will receive notifications.

This symptom is documented. Please let me know if there are any official documents or reference sites.
