✅ RESOLVED

CoroutineScope(<http://Dispatchers.IO|Dispatchers.IO>).launch {
    launch {
        println("A")
        delay(5000)
        println("B")
    }
    launch(context = Job()) {
        delay(1000)
        throw IOException()
    }
}

The above snippet will crash the android app (obviously), but the app prints B 5 seconds after the crash.
Note that removing Job() gives expected result. Any idea why? 🤔

I recommend this StackOverflow answer

The basic reason is that adding your own Job breaks the structured concurrency hierarchy and unlinks the coroutine from its parent.

Got it. Thanks Sam
