I'm surprised with the law being around for 2 years nobody has received the official guidance needed.

The law might have been around for 2 years, but in practice many smaller organisations didn't find out about it until a few months ago. Much of the official guidance is more recent even than that. And much of that guidance doesn't really help anyway, because it is often almost as vague and/or incomplete as the original regulations themselves. Questions about numerous everyday issues that will affect literally millions of businesses across the EU are still lacking useful answers.
