How do I stop Facebook Messenger from sending me double notifications?

[Android Central Question]

This started a week ago or so and I have never experienced it before.
Whenever somebody writes me on Facebooks Messenger app I get the normal notification that I've customed to only vibrate an otherwise be silent, BUT I also get another notification saying" X-person has send you a message" or close to that. This notification ignores all my settings and vibrates, play sounds and light up every single time. Whenever I press the weird notification it simply asks me to log-on to Messenger to see the text from X-person, despite it itself showing me that I am already logged in to my account.

Hope you can help because this is the most annoying thing I've tried with Facebook/Messenger, and that's saying something.

Which device?
You tried clearing cache and force stop Facebook?

Also, see if that second notification is coming from Chrome or any other browser after accessing FB Messenger page. Next time you get it long press the notification and see which app pushed it.
