According to the documentation here: https://developer.android.com/topic/google-play-instant/getting-started/instant-enabled-app-bundle#access-installed-apps instant apps should be able to launch installed apps if the action is ACTION_SEND, ACTION_SENDTO, or ACTION_SEND_MULTIPLE. However launching an intent with action ACTION_SENDTO does not work.

What are the steps to reproduce the problem?

Running the following code within an Instant app will not open the correct app and will cause an error to be logged.

  val intent = Intent(Intent.ACTION_SENDTO).apply {
    data = Uri.parse("mailto:example@example.com")
  }
  context.startActivity(Intent.createChooser(intent, "Send email"))

What was the expected result?

The code launches an email app.

What was the actual result?

The code does not launch anything and an ActivityNotFoundException is logged. The full log is below.
