I have recently upgraded to macOS Big Sur 11.0.1 from Catalina 10.15.7.
Now, when I receive a Message, I get the notification but I no longer reply through it. This used to work in Catalina.
I found no useful options in System Preferences > Notifications nor in Messages > Preferences.
Any idea why this is happening and/or what I could do to solve this?
It's a very important feature for my everyday workflow at the Mac.

You can reply, it's just not intuitive. When you receive the notification, click the dropdown option to expand/show more and it will give you a text field which you can type in.
