Push Notification don't work on iOS standalone app

Please provide the following:

  1. SDK Version: 35
  2. Platforms(Android/iOS/web/all): iOS

We recently upgraded our Expo project to SDK 35. Built our iOS standalone app with the command expo build:ios Submitted to TestFlight but the notifications don’t appear on iOS13 devices. Quite sure our implementation of notifications works because Android standalone apps are able to receive the notifications.

Is there anything we should look out for or make any changes to the code?
