Hello, I have trouble with Dispatchers.Main on Android. Here are my dependencies:

implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.2.1")
implementation("org.jetbrains.kotlinx:kotlinx-coroutines-android:1.2.1")

And on my activity, a simple launch would do nothing when ran on Dispatchers.Main, whereas it works on `Dispatchers.IO`:

GlobalScope.launch(Dispatchers.Main) { // Works with <http://Dispatchers.IO|Dispatchers.IO>
            Timber.d("Current thread: ${Thread.currentThread().name}")
        }

In debug, I can access Dispatchers.Main which is correctly plugged to the android handler.
Any idea what I'm doing wrong?

There should be nothing wrong with Dispatchers.Main on Android.
I'd advocate against using GlobalScope, as it doesn't account for structured concurrency. Try to launch your coroutine from the scope of an `Activity`/`Fragment`/`ViewModel`
