Can someone who knows the answer please respond to my question?
To ask the question again with different wording: I can successfully send push notifications to iOS and Android devices. In both cases, if the application is not running, notifications are delivered to the notification centre (iOS) or notification tray (Android). If I now open the application by tapping the application icon, any previously delivered notifications are NOT forwarded to the application. This is contrary to what the documentation says and contrary to a comment by @Uldris in another thread on this topic.
So, is it the expected behaviour that previously delivered notifications will be forwarded to the application (and I’m doing something wrong) or is the documentation incorrect?
