So did you spot the problem?
If not, we'll help you focus... it happens at the 10-second mark in the trailer, when the Minister Of Magic magics himself into existence at Hogwarts.
And therein lies the problem...

Yep, magically transporting - or, as it's known within the Harry Potter universe, "apparating" - cannot be performed on the Hogwarts grounds, as there is a magical spell that stops folks from doing it.
And Harry Potter fans did not let this point go unnoticed.

However, despite this, some folk have come to the rescue, trying to come up with reasons as to why the previously set rules are now being broken:

So was it an accidental oversight? Or were we shown it in the trailer for a specific reason, pointing it out as an upcoming plot point?
We'll know for sure when Fantastic Beasts: The Crimes Of Grindelwald is released in cinemas on 16 November.
