Well I haven't had any notification bugs since I downgraded back to 8.1. Maybe you are still on windows 10?
Notification bug still exists in WhatsApp, you don't get toast notifications for multiple group messages, alert tone and toast notifications are only working for the first message in a group and for preceding multiple messages you don't get a tone or toast notification. Only the tile gets updated with latest count of unread messages at once suddenly out of blue.
