This is regarding a push notification services.One of my app is not receiving push notifications after an update which it was receiving before the update. I have tried all the troubleshooting techniques provided by apple and resubmitted the app as well.Following test cases I have executed.1. Renew the Push certificate and updated PEM file with server.2. Re submitted the app by validating distribution profile and push certificates.3. App is not supporting iOS 10 upgrade, So entitlement file is not added in build.4. Server receiving a token from the App successfully and notification feedback also succeeded.My only concern is I am getting push notification in my app(downloaded from App Store) when manually sent as test badges from the same server but same is not getting pushed when sent from live scenario.Post if you need any other details to look into this further.Please help me on this.
