The fact that these kind of apps are able to survive longer than 10 minutes after being reported is frightening.

One may argue that there is some misunderstanding but at least immediately blocking the app in the country it undoubtedly misbehaves would be a very logical first step before digging deeper.

Why would Apple not do exactly that?

If Apple turned an investigation team onto the app and pointed all forensics at it, I could see reason for wanting to collect data before shutting it down.

Not that Apple is in the position to put someone under arrest, but I believe LE investigations sometimes allow suspects to walk free in order to observe and collect additional evidence.
