Con End-to-end encryption only in "Secret" conversations
If you want e2e encryption, you need to start a secret conversation.
Con Not very customizable
With so many features in one app, it's very possible you might not be a fan of at least one of them. Too bad you can't disable anything in settings.

Messenger has so many features accessible from one page that it is often difficult to find what you're looking for.
