Should an application show some in-app message after taping on a system notification?

In the case that the user ignores a system notification, the app in question:

• First shows a message saying the app status has changed.
• Then it updates its content after the user dismisses the message.

The problem occurs when the user taps on the system notification, in which case the app can either:

(A) Show right away the new content, or

(B) Show the same message to the user as in the case when the system notification is ignored, then update the content.

Which experience is better, if the content can be updated instantly without any delay (so that there isn't a progress indicator / any indication that the content has been updated)?
