If I install/run my app then on an iPhone with iOS 13 Voip pushes are not getting through to the app (the app is in the foreground, I saw the other thread about them not being delivered in the background). The server is configured to send pushes over the Apple dev environment.
However if I unplug the iPhone and replace it with one with iOS 12 then the pushes are delivered.
The same app is also available on the app store, if I download that and run it on the iOS 13 devices then it receives the pushes (of course as its on the app store the pushes are being sent over the Apple production environment).
The conclusion - Voip pushes are working for the Apple production environment with iOS 13 but not the Sandbox enviroment.
Anybody else observed the same?
