Adjusting notifications can be done in 2 different ways on Android. If you've tried one and your notifications and it doesn't appear to be working, please try the other method.

PLEASE NOTE:
It is not advised to turn off notification completely as this is a critical way to be notified you are under attack! 

Adjusting Notifications In-App

To adjust your In-App notification settings, head to the Settings Gear on the top left of the home screen.

You will find a number of notification check boxes for various features in the app!
Check or un-check the box you would like to edit and back out of the screen for the setting adjustment to take place.
