App users receive multiple notifications. But, We sent once.

Hello.

It seems that some customers are having a problem receiving Push notifications sent by our app.

There is only one transmission history on the server. Some users receive only one notification, while others receive multiple notifications. There are no in-app notifications, and all notifications are sent from the server.

Given this situation, we believe that there may be a problem on the OS side that receives the push notifications.

We would appreciate any solutions or information you can provide.

As an example, we will send you information on the actual push notification where the duplication occurred.

This is occurring on iOS16 as well as iOS17.

Thank you.

regards.

  1. File a bug report with Apple via the feedback app
  2. Open a ticket with your push notifications service provider. If that is also you, debug the server-side script for concurrency issues.
