When Notifications Stop Working After macOS Monterey Update

Recently, after updating my Mac to Monterey, notifications stopped coming through...

At first, I looked into what the problem might be, checked if Do Not Disturb mode was on, and tried various things, but nothing worked.

#How to Receive Notifications Again

First, go to System Preferences.

Then go to "Notifications & Focus".

Check if "When mirroring or sharing the display" is checked under "Allow Notifications" in the bottom right corner.

#Conclusion

For a while, I couldn't receive any work notifications because of this. There were so many problems, but it turned out this issue occurs when using DisplayLink. I'm writing this because if you use an M1 Mac like me, you'll probably encounter similar situations often.
