The legacy notifications had bugs too. If you had too many notifications, sometimes it would just be randomly cleared and unable to be recovered.

Additionally, legacy notifications had a limit to how many notifications it could have at a time and if you exceeded that limit, you'd have to keep pressing "mark all as read" and refresh, and repeat and rinse. Not sure on UCP notifications, though.
