Facebook's investor presentation shows MAU stay flat at 242 millions in Q4'18. I don't see a 15 millions drop.

(The numbers for DAUs and MAUs do not include Instagram, WhatsApp, or Oculus users)

Thanks for the link, very interesting document, it really shows an impressive scale.

And for the metrics, it's probably coming from the fact that a lot of people use Messenger without using Facebook, but it's still considered "using Facebook".
