[[Spoiler Alert]] Apparation during Battle on the Final Repository

If you haven't finish the main story, why are you here ? Otherwise, enjoy the spoiler

How did professors apparating inside of Hogwarts during Battle on the Final Repository ? It make no sense since we all know you can't apparate or disapparate inside of Hogwarts. I love the attention to details where Professor Fig won't apparate inside the Map Chamber because it's in Hogwarts which mean he can't. But the final main quest made me scratch my head and goes "WTF is that ?" How did professor Sharp, Weasley, Onai, Hecat and Ronen apparating to the final repository which is inside of Hogwarts ?

It was explained to us that protective spells most likely do not work under Hogwarts. Looks like you can apparating there.
Though in flashback, the professors definitely "walked" in the same place many years ago. So this is not really clear.
But to be honest, against the background of many, many other questions, this moment confuses me less than others :D

It's in the same vein as how the hell peeves stole some pages from the book? Apparently hogwarts protection don't extend to the chamber made with ancient magic. Make sense as it was added later after hogwarts already built.
