Not getting notifications from some apps on iOS 17.5.1

• Tested the pusher tool on a different device same OS version, There it is working.

There are many reasons for a problem like this to appear. The two most common reasons we see during development are:

1. building over and over from Xcode, your tokens may have changed and you are not aware of it. Try cleaning up. Delete the app from the device, and install a fresh build and test using the new tokens
2. if you are switching between debug and release builds, make sure that you are using the correct tokens and the correct APNs endpoints. development and production tokens are different and can only be used with the corresponding environments.

If these simple issues are not it, then you will need to look at any errors you are receiving, and if you cannot solve the issue, supply some detailed information about failing notifications.

@Engineer This issue is happening to applications which are on Production environment downloaded from app store. The token is also valid(Checked in Device Token Validator of CloudKit).

APNS is giving a success for the API, but it is not delivered to the app.

We have even tried resetting the location and privacy settings along with off loading the app. But still the issue persists. Please help.
