I cannot delete old notifications in the Creative Cloud App. This has been an issue for the last few versions. I am now running version 220.127.116.119. One of the notifications is a few months old, the other two years old. I also notice that if I uncheck the "Show Notifications" checkbox in the General Panel of the CC app that it is rechecked the next time I launch the app. Is anyone seeing similar behavior or know how to resolve this behavior?
