How many times does Hermione have to say it?

The first trailer for "Fantastic Beasts: The Crimes of Grindelwald" was released Tuesday. When fans weren't busy drooling over young Dumbledore (Jude Law) and checking out Grindelwald's (Johnny Depp) new look, they took a moment to fire off some "canon" blasts.

The problem is the shot toward the very start of the trailer, showing several people apparating onto Hogwarts grounds.

We've been told time and again that you can't apparate on Hogwarts grounds. That area qualifies as the Hogwarts grounds. The rule is apparently not new, circa the 20th Century timeline of these movies. We've been told it's always been the case.

So now there's a debate about it -- was it a plot hole? J.K. Rowling herself wrote the "Fantastic Beasts" scripts, so you'd think she'd know. Unless the shot was added in by director David Yates, but he too would also know.

It's probably well-thought-out, and the running theory seems to be that they lifted the rule for a visit from the Minister for Magic. We have seen that the enchantments can be lifted on certain occasions, like Apparition lessons. Dumbledore was not Headmaster in this era, he was still Professor of Transfiguration, but the Headmaster could lift the enchantment.

Fans lashed out on Twitter, debating what happened:

There must've been a good reason for the shot to be included so prominently in the trailer. Or maybe Rowling and Yates just assumed fans would understand the rule was lifted for an important visit from the Minister. "Fantastic Beasts 2" opens in theaters November 16th.
