	// 2020-10-08: It seems the initialisation code is quite fragile in general and should be kept simple.
	// For example, adding a loading screen as was done in this commit: https://github.com/laurent22/joplin/commit/569355a3182bc12e50a54249882e3d68a72c2b28.
	// had for effect that sharing with the app would create multiple instances of the app, thus breaking
	// database access and so on. It's unclear why it happens and how to fix it but reverting that commit
	// fixed the issue for now.
	//
	// Changing app launch mode doesn't help.
	//
	// It's possible that it's a bug in React Native, or perhaps the framework expects that the whole app can be
	// mounted/unmounted or multiple ones can be running at the same time, but the app was not designed in this
	// way.
