Message notifications

Hello, I currently have an M1 2020 13" macbook air, running on big sur version 11.1. I am no longer receiving notifications for messages in the upper corner of the screen. I have notifications turned on for messages, I have tried turning the settings off and on again, I have tried restarting the laptop multiple times, and I have used activity monitor to reset notifications/ messages. Does anyone have any other suggestions? I don't notice the notification in the dock very often so I really depend on the pop-up in the corner. Thanks!
